Why Your Brain Won’t Shut Up About the Life You Didn’t Live

If your brain won't shut up about that job you didn't take, OR that person you didn't marry, OR that life you didn't live... here's the fascinating neuroscience reason WHY & HOW to shush your brain!

In my thirties, I decided to stop writing books and move to Los Angeles to write TV and movie scripts.

In many ways, this was like deciding to become a professional lottery winner.

For about 18 months, it looked like I might actually pull off my LA dreams.

I somehow managed to snag meetings with important-ish people, many of whom wore sunglasses indoors.

The pattern:

• The indoor-sunglasses people would tell me they’d read my scripts and call them “Brilliant!”

• Then they’d disappear into the Hollywood ether, never to be heard from again.

It was like Tinder dating. But with more lying and worse rejection.

So for 18 months, I lived in this weird purgatory, where I was constantly “almost” successful.

Let me tell you: Almost is torture.

Almost is like constantly smelling delicious cake… but never getting to eat any of it.

Eventually, one producer offered me a job writing for an established sitcom. I considered this for about a week. Then turned it down.

Why?

Because I wanted to write in my own voice about things that actually mattered to me. And I worried that writing someone else’s sitcom would make me feel like a very well-paid ventriloquist dummy.

Eventually, on my 19th month in L.A., I packed up and moved back to N.Y. to refocus on book writing.

The plan worked out.

Some of my books went on to become big bestsellers.

In theory, I should feel completely at peace with my decision.

Right?

But nope.

My brain has decided to be a complete bitch about things.

Decades later, it still hasn’t shut up about how I should have stayed in L.A. longer. Tried harder. Made it work.

Every time I watch a good movie, or see a palm tree, or even hear the word “screenplay,” my brain starts harassing me:

• What if you’d stayed in L.A. for another year?

• What if you’d taken that sitcom job?

• What if what if what if?

It’s like having a really mean roommate in my head, whose only hobby is pointing out all the ways I’ve potentially messed up my life.

Maybe you do this too?

Maybe your brain has its own heavily bookmarked What-If Folder.

• The relationship that ended without the closure conversation.

• The job you quit before you could succeed or fail completely.

• The friendship that died after that one fight you never resolved.

• The version of yourself you were becoming before fear made you retreat.

These incomplete stories live in your head like ghosts who refuse to leave… because they haven’t figured out they’re dead yet.

Here’s why…

There’s a psychological phenomenon called the Zeigarnik Effect.

Back in the 1920s, a psychologist named Bluma Zeigarnik was sitting in a Viennese café watching waiters work when she discovered something weird.

The waiters could remember every detail of every yet-to-be-paid order. Perfectly. Every modification. Every request. Every word.

But once the bill was settled? Poof. The memory of the order and orderer vanished.

Zeigarnik found this so intriguing she decided to test it.

She gave two groups of people the same task.

One group she interrupted right in the middle.

The other group she let finish the task to completion.

The interrupted group wound up remembering their tasks 90% better than those who finished.

Yes. 90% better.

That’s not a rounding error. That’s your brain yelling, “HEY. WE’RE NOT DONE HERE.”

This became known as The Zeigarnik Effect. It’s the tendency for your brain to remember unresolved things far more vividly than completed ones.

This also explains why cliffhangers work on TV shows.

They trigger your Zeigarnik Effect to keep you hooked.

Think about it.

The most infuriating thing a show can do is end an episode right when something important is about to happen.

• Will Ross choose Rachel or Emily?

• Did Carrie sleep with Big?

• Is Tony Soprano actually dead in that diner?

Your brain cannot stand unresolved storylines because it can’t file them away as “complete.”

Television writers have essentially learned how to weaponize this quirk of human psychology.

But here’s some unexpected good news.

Interruption isn’t always the enemy.

In the right dose, it can actually make you more focused.

This is why the Pomodoro Technique works for productivity.

Haven’t heard of the Pomodoro Technique?

• It’s this thing where you work in short bursts with breaks, and it’s named after those little tomato timers.

Here’s how it works:

• You work for 25 minutes, then deliberately stop.

• Even if you’re in the middle of something.

• Even if you’re on a roll.

• You stop anyway.

This drives most people crazy at first. It’s like being forced to pause in the middle of a really good book.

But that interruption creates just enough mental tension to keep your brain engaged, so when you come back to the task, your focus is sharper than if you’d just powered through.

Your brain, it turns out, likes an open loop.

As long as it trusts you’re coming back to close it.

The problem starts when the loop feels abandoned.

When there’s no plan. No promise. No sense that the story will ever reach a satisfying ending.

That’s when your brain decides to keep those “What-If Files” open indefinitely…. just to nudge you to return.

And there’s a reason it does this.

Evolution made your brain a drama queen.

Back in our caveman days, we were constantly worried about lions, tigers and bears, oh my!

And so our ancestors’ brains evolved to obsessively track “unfinished threats,” because forgetting about the rustling bush was how you became another animal’s dinner.

But evolution didn’t fully update itself for modern life, where today’s “unfinished threats” are things like career mishaps and broken relationships.

So now your brain treats these decades-old decisions like active emergencies.

Plus there’s another culprit to blame.

Something called “Loss Aversion.”

Studies show that losses feel about twice as painful as equivalent gains feel good.

Meaning?

My sense of loss over my L.A. screenwriting career hits twice as hard as the actual joy of selling millions of books.

Loss aversion then teams up with its equally annoying friend: Negativity Bias.

This is our tendency to fixate on what went wrong far more intensely than what went right.

It’s why I can remember every word of a mean book review. But have to actively concentrate to recall the thousands of glowing book reviews.

It’s also why you can instantly remember every criticism your mother ever made…
but need a moment to recall the compliments.

Our brains are like bad accountants who mainly focus on debits… and conveniently lose track of all the credits.

I see this pattern with my clients all the time.

• There’s Susan, who finally left her cheating husband. But instead of celebrating her freedom, she keeps asking, “What if I’d been more understanding? What if I’d tried harder?” Her brain has completely forgotten the years she felt lonely and unseen. (More on this topic here.)

• There’s alo Steve, who passed on a house with foundation problems and asbestos. But all he can think about is the beautiful hardwood floors and how he should’ve offered more money.

Same brain pattern. Different life details.

So what can we actually do about this psychological harassment?

Here are 2 helpful tools.

1. The Question Swap

When your brain asks its favorite masochistic question: “What if I’d made different choices?” …. interrupt it.

Do a stop-and-swap!

Redirect to the far more useful question: What did those choices teach me that I couldn’t have learned any other way?

This works because it tricks your brain into being curious instead of punitive.

2. The Reset Button

This tool helps you to reframe your regret story.

Here's how I use it.

Let’s say my brain starts pestering me: “What if you'd stayed in L.A.?"

I immediately think about my fifteen-year-old son Ari.

Specifically, I think about this:

• Everything that happened before my son Ari was born had to happen exactly the way it did …in order for Ari to exist in this world.

• If I’d stayed in L.A., if I’d taken that sitcom job, there would be no Ari.

• And I wouldn’t trade my Ari for all the Oscars in Hollywood.

So Ari becomes my reset button. The thing that helps me to forgive everything that came before him.

Everybody has their own reset buttons:

• The rescue dog you got after the divorce. If he hadn’t cheated, no Buddy sleeping on your feet every night.

• The job you love, which you only applied for because you got laid off. No pink slip, no dream career.

• The best friend you met in line at the pharmacy, both picking up antidepressants. No breakdown, no Sarah.

Your reset button is whatever makes your brain shut up about the path not taken… because the path you took led to something you wouldn’t trade for anything.

My mildly hopeful ending….

Understanding the Zeigarnik Effect, loss aversion, and negativity bias hasn’t magically cured my “What-If” ruminations.

My brain still occasionally brings up L.A. like an overly enthusiastic dog dropping a tennis ball at my feet. Persistent, slightly annoying, and oblivious to the fact that I’m trying to eat dinner.

But now at least I understand what’s happening.

It’s not evidence that I did life wrong.

It’s just my brain doing what brains do. Trying to protect me with outdated software and terrible timing.

And remember:

We all have lives we almost lived.

But the life you’re actually living… the one with the strange choices, the wrong turns, the unexpected gifts, the moments that didn’t go according to plan…

That’s the life that matters most.

Even if your brain is still trying to catch up to it.
