Your brain deletes most of your ordinary days. It keeps almost every minute of a night alone in a foreign city. What's happening there is actually one of the more beautiful things about how your nervous system works.
Your brain is a prediction machine. When it can predict everything, like your commute, your kitchen, your same six streets, it stops recording. That's why whole months at home just vanish. But put yourself somewhere it can't predict anything and the system flips. Every sign, every smell, every crosswalk registers as new information. Dopamine tags all of it as worth keeping. This is why one week abroad feels longer in memory than a month at home. Your brain literally kept more of it.
The second thing happening is quieter. At home, some part of you is always tracking how you're being perceived. Your boss, your friends, the people who knew you at 22. In a city where nobody knows your name, that entire system goes offline.
And when it goes offline, the bandwidth doesn't disappear. It gets redirected inward.
That's the "realizing how far you've come" part. Your brain is finally recording again, the self-monitoring is off, and you're far enough away from your life to see the whole shape of it at once.
You spend years too close to your own life to see it. Then one night you're crossing a street on the other side of the world, and you finally have enough distance to look.
Suddenly, you're 27.
You make your coffee, rush to work, come home around 7, and you're too tired to do anything except eat, scroll on your phone, and pass out.
Then you wake up, and do it all again.
And when Friday comes, maybe you go out, or maybe you're just too tired. Then, out of nowhere, it hits you.
How did everything pass by so quickly?
You don't even feel 27.
You still feel like that 17 year old kid who thought they had all the time in the world.
But somehow, 10 years just disappeared. And you start missing the past. The feeling of being young, excited, and clueless.
But then you realize, one day, you'll miss this, too.
Being 25, being confused, being tired, but still trying.
So maybe the trick is to slow down a bit and actually live this chapter before it also becomes just another memory.
The point is no matter what age you are, you’ll miss these days. Life gets busy sometimes and it’s always a good time to stop and smell the roses.
