Quick Summary: Your brain is quietly editing the world around you right now and its deciding what you notice and what you don’t. Out of everything happening, it only lets a tiny fraction through, including opportunities, kindness, and evidence you’re capable. Learn the science behind why do I miss opportunities, plus a simple 2-minute daily exercise to reprogram your brain’s filter and start noticing what’s been there all along.
Your brain is filtering out 99% of your reality right now
11 million pieces of information reduced to just 40 that you consciously notice.
Not because it isn’t there. But because your Reticular Activating System decided, without asking you of course that it doesn’t matter.
And here’s what terrified me when I finally understood why do I miss opportunities: If my brain was hiding mushrooms from me for years, what else was it hiding?

It All started with a Mushroom
Last week, I saw a photo of a bright red mushroom with white spots on Facebook. Scrolled past it. Thought nothing of it.
The next day, my husband and I were out walking. And there it was, that same type of mushroom. Just sitting there in the grass like it had been waiting for me.
“Look!” I pointed. “It’s the mushroom from Facebook!”
We spent an hour hunting for more. Taking photos. Laughing at ourselves for caring this much about fungi we’d never noticed before.
But here’s the thing that shook me: Those mushrooms were always there.
I’d walked that path dozens of times. But I’d never seen them. Not once.
Until I saw one on Facebook. Then suddenly, they were everywhere.
My brain had been filtering out mushrooms my entire life. Not because they weren’t there, but because I’d never told my brain they mattered.
And if my brain was filtering out mushrooms… what about opportunities? Connections? Proof that I’m capable? Evidence that contradicts every limiting belief I’ve been carrying around?
Right now, as you read this, your brain is filtering out something that could change your life.
You just don’t know to look for it yet.
Here’s what keeps me up at night: You’re making decisions based on incomplete information. Choosing jobs, relationships, habits—all while your brain hides 99% of reality from you.
And the worst part? You think you’re seeing clearly. You think your pessimism is realism. Your cynicism is protection. Your belief that “opportunities never come” is just… accurate observation.
But what if it’s not? What if you’re just filtering out the mushrooms?
Why Do I Miss Opportunities? What Else Have You Been Filtering Out?
Mushrooms are harmless. Kind of funny, actually.
But here’s what terrified me once I understood what was happening:
If my brain was filtering out mushrooms I didn’t know to look for… what about opportunities? Connections? Possibilities? Kindness?
What if the life I thought was “reality” was just… the 1% my brain decided to show me?
And worse—what if I’d programmed my brain to show me the worst 1%?
I started noticing this everywhere. In myself. In people around me.
Friends who only see corruption and greed, because that’s what they’re primed to notice.
Family members convinced “nobody cares anymore”—missing acts of kindness happening right in front of them.
People stuck in “I’m not good enough”, filtering out every piece of evidence that contradicts it.
They’re not wrong. Corruption exists. Selfishness exists. They have plenty of evidence.
But they’re also filtering out the mushrooms.
The opportunities. The connections. The proof that they are good enough.
It’s all there. They just can’t see it. Because nobody told their brain to look for it.
How Does Your Brain Decide What You See?
This isn’t mystical. It’s neurological.
Your brain has a filtering system called the Reticular Activating System (RAS). Its job is to decide what deserves your conscious attention.
Every second, your brain is bombarded with 11 million pieces of information. Your RAS filters this down to just 40-50 pieces that reach your conscious awareness. If you processed all of it, you’d be paralyzed.
So your RAS filters out 99% of reality. It only shows you what it thinks matters.
And how does it decide what matters?
Whatever you’ve told it to look for. Through repetition and focus. Through the beliefs you’ve inherited and never questioned.
Once your RAS is primed to notice something—red cars, corruption, rejection, mushrooms—you’ll see it everywhere.
Psychologists call this the frequency illusion or the Baader-Meinhof phenomenon.
But here’s what nobody tells you: It works both ways.
If you can program your brain to see mushrooms… you can program it to see anything.
Why Your Brain Works This Way
The RAS evolved as a survival mechanism. Your ancestors needed to filter for threats—predators, poisonous plants, dangerous weather. Your modern RAS still operates this way, but instead of filtering for saber-tooth tigers, it filters for whatever you’ve repeatedly focused on: rejection, scarcity, failure.
According to research published in the National Center for Biotechnology Information, the RAS is responsible for regulating arousal, maintaining consciousness, and determining which sensory information reaches your awareness. As neuroscientist Duje Tadin from the University of Rochester explains, “Before attention gets to do its job, there’s already a lot of pruning of information.”
The mushrooms were always there—your RAS just decided they didn’t matter to your survival.
The Filters You Inherited (And Never Questioned)
For years, I filtered out connection.
I’d go shopping and choose self-checkout every time. Why deal with the awkward small talk? The cashier is only talking to me because I’m a customer, right?
That was my filter: Interactions are transactional. People don’t actually care.
I didn’t choose that belief consciously. I absorbed it. From family and experiences I interpreted through a certain lens. From years of reinforcement.
And once it was programmed in? My brain showed me evidence everywhere. Every forced smile, every scripted “have a nice day,” every hurried interaction.
The filter was confirming itself.
Same with “I’m not good enough.” Nobody sat me down and said those exact words. But that was the message, subtle and constant, growing up. And my brain? It filtered reality to prove it true.
Every time someone didn’t respond to a message—proof.
I didn’t get picked— more proof.
Every time someone seemed distant—proof.
Meanwhile, evidence of the opposite was everywhere. I just couldn’t see it. I was looking for mushrooms I’d never been taught to notice.
Pause here: What’s one thing you complain about seeing everywhere? Traffic? Rudeness? Bad luck? That’s not reality—that’s your filter showing you what it’s been programmed to find.
What Filters Are You Running That You Didn’t Choose?
- “Money is the root of all evil” → Your brain shows you every greedy rich person, filters out every generous one
- “Everything is corrupt” → You see corruption everywhere, miss acts of integrity
- “People are selfish” → You notice every rude driver, every inconsiderate act, filter out every kindness
- “Opportunities never come to me” → You miss openings right in front of you because your RAS isn’t looking for them
- “I’m not good enough” → You filter for rejection, miss every piece of evidence that contradicts it
You’re not seeing reality. You’re seeing the 1% your filter was programmed to show you.
And the worst part? It feels like truth. Because your brain has 20 years of evidence confirming it.
Sound familiar?
What Happens When You Reprogram the Filter
These days, I go to the checkout with a person. Not every time, sometimes I’m in a rush.
But most days? I choose the till.
Same store. Same action. Completely different experience.
Because I reprogrammed my filter: Interactions are opportunities for connection.
Now I notice:
The cashier who remembers my usual order.
The stranger who holds the door and actually means their “have a good day.”
The person who lets me merge in traffic and waves.
They were always there. Always. But my old filter hid them.
And here’s the wildest part: Once I started noticing connection, people started being more connected. Not because people changed but because I changed what I was looking for.
The filter doesn’t just show you what’s there. It shapes what you create.
When you filter for rejection, you act guarded. People sense it. They pull back. Your filter confirms itself.
When you filter for connection, you act open. People respond. They lean in. Your filter confirms itself.
Same world. Different filter. Completely different life.

The 2-Minute Morning Exercise That Reprograms Your Filter
Here’s the exercise that changed everything for me.
Every morning, before you check your phone, ask yourself ONE question:
“What’s one [your mushroom] I can notice today?”
That’s it.
For me, it was: “What’s one connection I can notice today?”
Not create. Not force. Just… notice.
Then I’d go about my day. And every time I noticed a connection, however small I’d mentally note it. The person who smiled. The colleague who asked how my weekend was and actually listened. The barista who made my coffee exactly right.
That’s phase one: Notice.
Phase two happens at night.
Before bed, I’d write down three connections I noticed that day.
Just three. No essays. Just:
- Cashier remembered my name
- Neighbor waved
- Friend texted to check in
This is the reprogramming happening in real time.
You’re training your RAS to look for your mushroom. And once it starts looking? It finds them everywhere.
Within two weeks, my filter had shifted.
Within a month, it felt automatic.
I wasn’t trying to see connection anymore. I just… did.
How Long Does It Take?
Neuroplasticity research shows it takes 7-14 days for your brain to start forming new neural pathways.
But here’s what nobody tells you: Days 5-7 are the worst.
Your old filter fights back. You’ll notice fewer mushrooms than day one. You’ll think it’s not working.
This is when most people quit.
Push through. Days 8-14, things click. By day 21, the new filter feels natural.
By day 30? You won’t remember what the old filter felt like.
Research shows that forming a new habit or mental pattern takes around 66 days on average, though it can vary depending on how often you practise and how emotionally rewarding it feels. The point isn’t to rush it; it’s to stay consistent long enough for your brain to realise the new filter matters.
Why This Works When “Positive Thinking” Doesn’t
I still practise journaling and gratitude every day, and they work.
They shift your emotional state, build awareness, and train your focus toward what’s already good.
But here’s where the Mushroom Effect stands out.
Gratitude helps you appreciate what you’ve already seen.
The Mushroom Effect helps you start seeing what you’ve been missing.
Gratitude strengthens appreciation; the Mushroom Effect changes perception. It works a layer deeper, at the level of what your brain even allows into awareness.
So while gratitude reshapes how you feel about your life, the Mushroom Effect reshapes what you notice in the first place. And once you start noticing differently, gratitude has more to work with , it starts to feel genuine instead of forced.
The Decision-Making Problem Nobody Talks About
Here’s where this gets dangerous.
Every decision you make in your career, relationships, where you live, how you spend your time is based on the information your RAS shows you.
But your RAS is only showing you 1% of reality.
Which means you’re making decisions with 1% of the data.
And if that 1% is filtered through beliefs you inherited and never questioned? You’re making decisions based on someone else’s filter.
Your parents’ filter, your culture’s filter and past self’s filter.
Think about the last major decision you made. Maybe where to live, whether to take a job, whether to end a relationship.
What information did your brain filter out?
What opportunities did you miss because your RAS wasn’t looking for them?
Did you overlook people because your filter said “they’re not interested”?
What possibilities did you dismiss because your filter said “that’s not for people like me”?
You’ll never know. Because you can’t see what your brain filters out.
Unless you reprogram the filter.
Change Is Scary When You’re Filtering for Danger
I get it. Change is terrifying.
But here’s what I realized: Change was only terrifying because I was filtering for what could go wrong.
Every time I thought about making a change, starting a business, moving cities, ending a relationship—my brain would helpfully provide a highlight reel of every possible catastrophe.
That wasn’t insight. That was my filter.
My RAS was programmed to look for danger. So that’s all it showed me.
When I reprogrammed my filter to look for possibility instead? Change felt different.
Not easy. Not risk-free. But… possible.
Because now my brain was showing me the ways it could work, not just the ways it could fail.
If you’re stuck in analysis paralysis, constantly overthinking every decision, or terrified of change—it’s not because you’re being “realistic.” It’s because your filter is showing you a very specific (and incomplete) version of reality. I’ve written extensively about how to overcome the fear of change and why our brains resist it, even when staying stuck is worse.
The Overthinking Trap
Ever notice how you can spend hours analysing the same problem and get nowhere?
That’s your filter at work.
You’re not actually analysing. You’re ruminating your going over the same filtered information again and again, hoping to find a different answer.
But you can’t find a different answer with the same data.
Your RAS is showing you the same 1%. Over and over. Forever.
Breaking the overthinking cycle isn’t about thinking better—it’s about changing what your brain shows you in the first place. When you’re stuck in your head, journaling for overthinking can help you externalize those repetitive thought patterns and interrupt the filter that keeps replaying them.
The Mushroom Exercise breaks this loop.
By actively looking for something new each morning, you’re forcing your RAS to show you different information.
Different information = different analysis = different decisions.
The Exhausting Cost of Decision Fatigue
Here’s another thing I noticed: The more my filter showed me problems, the more decisions I had to make.
Every interaction became a decision: Should I trust this person? Are they being genuine? What do they want from me?
Every opportunity became a decision: Is this a trap? What’s the catch? What could go wrong?
Hundreds of tiny decisions. Every day. All because my filter was set to “threat.”
No wonder I was exhausted.
When I reprogrammed my filter? The decisions got easier.
Not because I became reckless. But because my brain was no longer flagging everything as a potential threat that needed analysis.
Most things could just… be.
If you find yourself mentally drained by the end of each day, constantly weighing options and second-guessing yourself, you might be experiencing what researchers call decision fatigue—the deteriorating quality of decisions after making many choices. I’ve explored how to overcome decision fatigue and preserve your mental energy for what actually matters.
What Does a “Good” Filter Look Like?
Let me be clear: You don’t want to filter out all problems.
Some things are threats there are people that are manipulative. Some opportunities are traps.
The goal isn’t to see everything through rose-colored glasses.
The goal is to see accurately.
Right now, your filter is showing you a heavily edited version of reality. Probably skewed negative (because that’s what kept your ancestors alive).
A good filter shows you:
- Problems and solutions
- Threats and opportunities
- Rejection and connection
- Failure and growth
- What’s wrong and what’s working
You’re not aiming for positivity. You’re aiming for completeness.
And here’s what shocked me: When I started filtering for the full picture? Life wasn’t easier.
But it was… possible.
Problems still existed. But so did solutions.
Obstacles still appeared. But so did paths around them.
The mushrooms were always there. I was just finally seeing them.
How Your Filter Creates Your Reality (Not Just Reflects It)
This is the part that broke my brain.
Your filter doesn’t just show you what’s there.
It actually shapes what happens.
Because when you filter for rejection, you act differently. You’re guarded. Defensive. You pull back before someone can reject you.
And people sense it. They respond to your guardedness with distance. Which your filter then flags as “proof” of rejection.
The filter creates the very evidence it’s looking for.
Same with opportunity.
When you filter for “opportunities never come to me,” you stop looking. You dismiss openings as “not for someone like me.” You don’t follow up. You don’t ask.
And then… opportunities don’t come.
Your filter isn’t reflecting reality. It’s constructing it.
Change your filter, and you don’t just see different things. You create different things.
The Social Proof Problem
Here’s what makes this so insidious: Your filter is reinforced by social proof.
If you filter for “people are selfish,” you’ll notice every selfish act and bond with others over it.
“Can you believe how rude people are these days?”
“Nobody cares anymore.”
“It’s all about me, me, me.”
And everyone agrees. Because they’re filtering for the same thing.
Your filter is validated. Strengthened. Locked in.
Meanwhile, the person filtering for kindness? They’re noticing generous acts. Bonding with others over that.
“Did you see how that stranger helped?”
“People are so thoughtful.”
“There’s still good in the world.”
Same world. Different filter. Different social proof.
Which filter do you want to be locked into?
Your Children Are Learning Your Filter
If you have kids, this one will hit hard.
Children don’t inherit your beliefs through lectures or rules.
They inherit them through observation.
They watch what you notice. And they learn to notice the same things.
If you filter for danger, they learn to filter for danger.
Filter for scarcity, they learn to filter for scarcity.
If you filter for “I’m not good enough,” they learn to filter for “I’m not good enough.”
Your filter becomes their filter.
And they’ll carry it for decades. Filtering out opportunities, connection, proof of their worth.
Just like you did.
Unless you reprogram yours first.

The Practical Exercise: Finding Your Mushroom
Okay. Theory is one thing. Let’s make this practical.
Choose Your Mushroom
What’s ONE thing you want to start noticing?
Not ten things. ONE.
Examples:
- Connection (my mushroom)
- Opportunity
- Kindness
- Evidence you’re capable
- Solutions (not just problems)
- Progress (not just setbacks)
- Generosity
- Synchronicity
- Beauty
- Possibility
Pick the one that makes you go “I never see that.”
That’s your mushroom.
Ask the Morning Question
Every morning, before checking your phone:
“What’s one [your mushroom] I can notice today?”
Don’t answer it. Just ask it.
Let your brain go find the answer throughout the day.
Notice Without Judgment
As you go through your day, notice when your mushroom appears.
Don’t force it. Don’t manufacture it. Just notice.
The barista smiled, that’s connection.
Someone let you merge in traffic, that’s kindness.
You solved a problem at work, that’s evidence you’re capable.
Mental note. That’s it.
The Evening Three
Before bed, write down three mushrooms you noticed.
Three. Not five. Not one. Three.
Why three? Enough to rewire your brain. Not so many it becomes a chore.
Repeat for 21 Days
The first week will feel awkward.
Week two, you’ll notice more mushrooms without trying.
By week three, your filter has shifted.
This is neuroplasticity in action.
The Resistance You’ll Face (And How to Push Through)
Around day 5, your brain will rebel.
You’ll notice fewer mushrooms than day one.
You’ll think: “This isn’t working. I knew it was bullshit.”
This is the old filter fighting to survive.
It’s been running your life for years. It’s not giving up without a fight.
Push through.
Day 5-7 is when most people quit.
Day 8-10 is when the breakthrough happens.
By day 14, you’ll wonder how you ever saw things the old way.
The resistance is proof it’s working. Not proof it’s failing.
What to Do When Someone Challenges Your New Filter
Here’s what’ll happen:
You’ll start noticing connection, or opportunity, or kindness.
And someone will say: “You’re being naïve. People aren’t actually like that. You’re just seeing what you want to see.”
They’re right. And wrong.
Yes, you’re seeing what you’re looking for.
But so are they.
They’re filtering for cynicism, betrayal, selfishness. And their brain shows them exactly that.
You’re filtering for connection, possibility, kindness. And your brain shows you exactly that.
Neither of you is seeing “objective reality.” Because there’s no such thing.
You’re both seeing your filtered version.
The question isn’t “whose filter is right?”
The question is: “Whose filter creates a life I actually want to live?”
Drop your mushroom below: What’s ONE thing you’ll start noticing tomorrow morning? Just one word. (Mine was ‘connection.’)
This Isn’t About Pretending Everything Is Perfect
Look, I’m not telling you corruption doesn’t exist. Or that shitty people aren’t real. Or that your problems are imagined.
But your old filter wasn’t showing you “reality.” It was showing you a heavily edited version that confirmed your beliefs.
The mushrooms were always there. You just couldn’t see them.
The new filter isn’t “more positive” it’s more complete.
You’re not ignoring problems, but you’re finally seeing that solutions, kindness, and opportunity exist alongside them.
You’re not denying that people can be selfish but you’re noticing that people can also be generous and you’ve been filtering that out.
This isn’t about being naïve. It’s about being accurate.
And here’s the truth: If you only see corruption, poverty, and bad luck that’s not insight. That’s a filter.
You’re filtering out the mushrooms. And wondering why you keep walking in circles.
Traditional Positive Thinking vs. The Mushroom Effect
| Traditional Positive Thinking | The Mushroom Effect Method |
|---|---|
| “Think more positively” | “Train your brain to notice what’s already there” |
| Feels forced and fake | Feels like discovery |
| Ignores reality | Expands what you see as reality |
| No neurological basis | Based on RAS and neuroplasticity research |
| Requires constant effort | Becomes automatic after 21-30 days |
| Focuses on thoughts | Focuses on what you notice |
Why This Matters for Everything Else
Once you understand the Mushroom Effect, everything changes.
Weight loss? If your filter is set to “I can’t lose weight” or “my body doesn’t change,” you’ll filter out every small win. The better sleep. The increased energy. The way your clothes fit differently. You’ll only see the scale—and if it doesn’t move, you’ll think nothing’s working. But change your filter to “my body is adapting daily,” and suddenly you’ll notice progress everywhere.
Career opportunities? If your filter is “opportunities never come to me,” you’ll miss the colleague who mentioned a project, the networking event you scrolled past, the skill you could learn that would open doors. But change your filter to “I’m surrounded by possibilities,” and your RAS will start flagging them.
Relationships? If your filter is “people don’t really care,” you’ll miss every text checking in, every small kindness, every moment of genuine connection. But change your filter to “connection is everywhere,” and you’ll see what was always there.
This isn’t about positive thinking. It’s about accurate thinking.
Your current filter isn’t showing you truth—it’s showing you confirmation of beliefs you never chose.
Common Mistakes When Reprogramming Your Filter
Trying to change everything at once. Pick ONE mushroom. Not ten. Just one.
Expecting immediate results. Neuroplasticity takes 7-14 days minimum to start making connections. Your filter won’t shift overnight.
Thinking this is positive affirmations. It’s not. You’re training perception, not forcing thoughts.
Giving up at day 5-7. This is when most people quit—right before the breakthrough. Push through the awkward phase.
The Mushroom That Started Everything
I keep thinking about those mushrooms.
They were always there. Every walk I took. Every path I travelled. For years.
And I never saw them. Not once.
Until one Facebook post primed my brain to notice. Then suddenly, mushrooms everywhere.
That’s when I realized: If I can miss mushrooms right in front of me for years… what else am I missing?
Opportunities. Connections. Kindness. Proof that I’m capable. Evidence that life isn’t just corruption and despair.
It’s all there. I just have to notice one. Then suddenly, it’s everywhere.
Same world. Different filter.
The mushrooms were always there.
You just have to see the first one.

Mr Critic Moment:
“Right… so you think spotting a few mushrooms is going to rewrite your entire personality? Adorable. Next you’ll be manifesting parking spaces.”
That’s the trap he sounds reasonable. Logical, even. But Mr Critic doesn’t deal in facts; he deals in familiarity. He’d rather you stay blind than risk being wrong about yourself.
So smile, nod, and keep walking. Let him mutter. Because once you start noticing the first few opportunities, even he won’t be able to deny they were always there he just refused to look.
If you don’t really “hear” an inner critic, that’s okay for some of people, it’s not a voice at all. It’s the tightness in your chest before you act, the wave of hesitation before you speak up, or that quiet pull back when something good is offered. It’s the same filter, just felt instead of heard.
If You’re Feeling Regret Right Now
Maybe you’re thinking: “I’ve wasted years. All those opportunities I missed. All that time filtering for the wrong things.”
I get it. When I realized I’d been filtering out connection my entire adult life, I felt sick. How many conversations did I avoid? How many friendships never started because I chose self-checkout?
But here’s the truth: You weren’t broken. You weren’t stupid and you weren’t failing.
You were operating with a filter you inherited. A filter you never chose. And you couldn’t reprogram what you didn’t know existed.
The mushrooms were always there. They’re still there. And today-right now-is the first day you know to look for them.
You haven’t wasted time. You’ve been gathering evidence that it’s time to change your filter.

Journaling Prompts:
What’s one belief or “truth” I’ve been treating as fact that might just be a filter?
When was the last time I noticed something new that had always been there — and what did it teach me about awareness?
If I could train my brain to see one new “mushroom” starting tomorrow, what would it be — and why does it matter to me?
You have two choices right now.
Choice 1: Close this tab. Keep your current filter. Keep seeing what you’ve always seen. Watch another month go by wondering why nothing changes.
Choice 2: Pick your mushroom. Right now. Not tomorrow. What’s ONE thing you want to start noticing? Write it down. Ask yourself the question tomorrow morning.
That’s it. One mushroom. Two minutes. Tomorrow morning.
Which choice are you making?
Your Turn: Find Your Mushroom
What’s ONE thing you want to start noticing? One filter you want to reprogram?
Drop one word in the comments—just the filter you’re choosing. (Mine was “connection.”)
Let’s find our mushrooms together.

Frequently Asked Questions
What is the Reticular Activating System (RAS)?
The Reticular Activating System (RAS) is a network of neurons in your brainstem that acts as your brain’s filtering system. It processes 11 million pieces of information per second but only allows 40-50 pieces into your conscious awareness. The RAS decides what you notice based on what you’ve programmed it to consider important. According to research published by the National Center for Biotechnology Information, the RAS is responsible for regulating arousal, sleep-wake transitions, and determining which sensory information reaches conscious awareness.
How long does it take to reprogram your brain to see opportunities?
Neuroplasticity research shows meaningful changes begin within 7-14 days of consistent practice. Most people notice significant shifts in what they automatically see within 21-30 days of the 2-minute morning and evening Mushroom Exercise.
Why do I miss opportunities right in front of me?
Your brain’s RAS is filtering out opportunities because you haven’t programmed it to look for them. When your filter is set to notice problems, rejection, or scarcity, your brain literally hides evidence of opportunities, kindness, and possibility—even when they’re directly in front of you.
Is the Mushroom Exercise the same as positive thinking?
No. Positive thinking asks you to think differently about the same filtered reality. The Mushroom Exercise reprograms what your brain shows you in the first place. You’re not forcing optimism—you’re training your RAS to notice evidence that was always there but previously filtered out.
What is the Baader-Meinhof phenomenon?
The Baader-Meinhof phenomenon (also called frequency illusion) is when you notice something once, then suddenly see it everywhere. This happens because your RAS has been activated to filter for that specific thing. The mushroom story is a perfect example of this cognitive bias in action.
Have you experienced your own “mushroom moment”—where suddenly seeing one thing made you notice it everywhere? Share your story below. I read every comment.
You don’t have to rewrite your whole story overnight. Just start by noticing one new thing — one mushroom — and let your brain do the rest.
