You were tired at 4 pm.
Genuinely, dangerously tired.
The kind of tired where you briefly considered whether it would be acceptable to put your head down on a public surface.
It was not acceptable.
You waited.
You came home.
You changed into clothes that exist solely to be slept in.
You got into a bed that you have been thinking about since approximately 2 pm.
You closed your eyes.
And then your brain, which had been completely useless all day, suddenly remembered it had things to do.
This is not a sleep disorder.
This is not a medical condition requiring immediate attention.
This is just your mind, finally quiet enough to hear itself, discovering it has a great deal to say.
The first thought is always innocent enough.
Something small.
Something you forgot to reply to.
Something you said six years ago at a work event that nobody remembers except you, and you, and the version of you that apparently lives specifically in the twenty minutes before sleep and exists only to bring this up.
From there, it escalates quickly.
The forgotten reply becomes a missed opportunity.
The missed opportunity becomes a pattern.
The pattern becomes a personality trait.
The personality trait becomes a fundamental question about the direction of your life.
All of this happens before 11:15 pm.
Neuroscientists call this “default mode network” activation, which is the brain’s tendency to become most analytically active precisely when you are trying to shut it down.
It is, in the most technical sense possible, your brain doing its job at entirely the wrong time.
Think of it as a very dedicated employee who only sends their best work at midnight.
You did not ask for this employee.
You cannot fire them.
They do not respond to emails.
The Russian novelist Leo Tolstoy once observed that everyone thinks of changing the world, but no one thinks of changing himself.
He was not writing about sleep.
But at 11:30 p.m., when you are redesigning your entire career in your head while lying in the dark, it feels relevant.
Because the thoughts that arrive at bedtime are never really about what they appear to be about.
The forgotten email is not about the email.
The thing you said six years ago is not about six years ago.
They are the mind’s way of processing everything it politely set aside during the day because there were things to do, meetings to attend, and a general social agreement to maintain that you were fine.
Night removes all of that.
And what is left is just you, the ceiling, and everything you have been quietly carrying.
There is a term in psychology called “cognitive arousal,” which refers to the mental stimulation that occurs when the brain engages with emotionally significant material.
The irony is complete and merciless.
The more significant the thought, the more alert the brain becomes.
The more alert the brain becomes, the less likely it is.
The less likely sleep is, the more you think about the fact that you are not sleeping.
The more you think about not sleeping, the more significant that becomes.
And now you are thinking about thinking about not sleeping, which is its own special achievement.
At some point around midnight, you decide to check your phone.
Not for any reason.
Just to see.
The phone is not helpful.
The phone is never helpful.
The phone contains news, notifications, and the particular blue light frequency that signals to your brain that it is noon and time to be productive.
You put the phone down.
You pick it up again immediately.
You put it down with more conviction this time.
You stare at the ceiling with the quiet dignity of someone who has made a decision and is already reconsidering it.
The ancient Stoics had a practice called the “evening review,” where they would mentally walk through the day before sleep, not to judge it, but simply to see it clearly.
Marcus Aurelius did this.
Seneca wrote about it.
The idea was not to solve the day but to release it.
To acknowledge what happened, set it down, and trust that tomorrow was a separate thing entirely.
It is, genuinely, an excellent idea.
It is also completely impossible when your brain has decided that 12:17 am is the right time to finally think clearly about a decision you have been putting off for three weeks.
You will try the evening review next time.
You have been saying this several times.
Eventually, somewhere between exhaustion and surrender, sleep arrives.
Not because you achieved anything.
Not because you resolved the thoughts.
But because the body, unlike the mind, has limits.
And the body, eventually, wins.
You wake up tired.
You move through the morning on something that is not quite energy but is close enough to function.
By 4 p.m., you are genuinely, dangerously tired again.
The bed is hours away.
You think about it anyway.
Tonight, you tell yourself, will be different.
Tonight you will not check your phone.
Tonight you will do the evening review.
Tonight, you will simply close your eyes and drift off like a person who has their life together.
And you will mean every word of it.
Right up until 11 pm, when your brain clears its throat and asks if you remember what you said at that work event in 2018.
You do.
You always do.
If you recognize the pattern of having an excellent plan and watching it collapse by Tuesday, Why I Let AI Plan My Entire Week is a very honest account of what happened next. And if you have ever lain awake wondering whether you are the only one quietly carrying more than you let on, The Best Gift I Ever Received might be worth reading in the morning, when the ceiling has nothing left to say.
