What Entrepreneurs Can Learn from Why We Sleep
Treating sleep as the first thing to cut when the to-do list is long is the specific trap Why We Sleep names; the founder who cuts sleep to get more done usually gets measurably worse decisions out of the extra hours, without feeling any less confident in them.

The core lessons, applied to you
Protect a consistent sleep and wake schedule
Going to bed and waking at consistent times, even during a demanding stretch, supports steadier thinking than an irregular schedule with occasional long nights.
A founder sleeps in on weekends to recover from a stretch of late nights, which feels restorative but actually makes the following week's schedule harder to stabilize.
Pick one anchor time, either your wake time or your bedtime, and hold it steady for the next week even on lighter days.
Recognize how sleep loss quietly degrades thinking, mood, and decisions, even when you feel fine
Sleep-deprived judgment often doesn't feel impaired from the inside, which is exactly why a tired founder can make a genuinely bad call while feeling completely confident about it.
A founder makes a significant hiring or pricing decision at the end of a short-sleep week, feels certain about it in the moment, and only recognizes the flaws in it once well-rested again.
Before a significant decision after a run of short nights, delay it by a day if you can, and notice whether your view changes once you're rested.
Build a wind-down routine that actually supports falling and staying asleep
A calmer, more consistent routine before bed, with less late-night screen and work stimulation, makes it easier to actually fall and stay asleep even on a busy schedule.
Moving fast on the business and protecting your sleep aren't opposites — the hours saved by cutting sleep are usually paid back, with interest, in worse decisions the next day.
Name one thing, honestly
Is there a recent decision you made during a short-sleep stretch that you'd make differently now?
Good. Now look back at the "Try this" line under whichever lesson feels most connected to what you just wrote, and treat that as this week's actual assignment — not all 3 at once.
