For about fifteen years of my career, "I ran on five hours last night" was practically a boast. I'd say it the way other guys mentioned a personal record at the gym — a little too casually, waiting for someone to be impressed. High school principal, then superintendent, up at 4:45, in bed well past eleven most nights because there was always one more thing: a budget line to check, a discipline case to think through, a board member to call back. I wore the exhaustion like a medal. It said I care more than the people who are sleeping.
Nobody warned me the medal was actually a receipt. And receipts, eventually, get collected on.
What the Research Actually Says, Which I Ignored for Years
I finally read Matthew Walker's Why We Sleep this year — reviewed it a few days ago, in fact — and it wrecked the story I'd been telling myself for two decades. Walker, a neuroscientist who has spent his career studying sleep, lays out the evidence plainly: chronic short sleep isn't a minor inconvenience you push through. It measurably degrades memory consolidation, immune function, emotional regulation, and — this is the one that got me — the brain's ability to clear a protein called beta-amyloid overnight, the same protein implicated in Alzheimer's. Five hours a night for fifteen years isn't grit. It's a loan against a body that eventually calls it due.
Here's the part that stung most: I would never have run the shop that way. Ten years fixing cars taught me that you don't defer maintenance and call it toughness. You change the oil on schedule because skipping it doesn't save you money — it just moves the cost downstream and adds interest. I understood that completely about a transmission. It took me until my sixties to apply the same logic to my own nervous system.
The Rest Nobody Told Me to Take Daily
I've written before about Sabbath as a weekly declaration, and I still believe that with my whole chest. But somewhere in preparing that post, I realized I'd made rest into something I schedule once a week and then ignore the other six nights. That's not what the Psalms describe. "He grants sleep to those he loves" (Psalm 127:2, NIV) isn't a verse about Sundays. It's describing something nightly — a rhythm built into creation itself, the same rhythm that shows up in Genesis before humanity does anything to earn it. God rests on the seventh day, sure. But He also built an entire nervous system that needs to power down every single night, no negotiation, no productivity hack around it.
"He grants sleep to those he loves." — Psalm 127:2 (NIV)
I used to read that as a nice sentiment for anxious people. I read it now as an indictment of how I spent my thirties and forties — treating a gift as an obstacle, and bragging about how little of it I'd accept.
Let's Be Honest — I Still Fight This
I'd love to tell you I've fully repented. I haven't. Learning to fly has put a fresh version of the old pattern back in front of me — study materials at 10 p.m., the same old itch to squeeze one more hour of "productive" time out of a day that's already full. My wife caught me at it three weeks ago, phone lit up in bed, "reviewing airspace regulations" at 11:40. She didn't say much. She just reached over and turned the phone face-down. Forty-two years in, she still knows exactly when I'm running up a debt I'll be paying down for a week.
What makes it harder to catch is that the old identity is still in there somewhere, whispering that the guy who needs eight hours is soft compared to the guy who used to run schools on five. That voice is lying to me. It's the same voice that used to tell me deferred maintenance on a customer's car was fine as long as nothing had broken yet — technically true, and a terrible way to run anything you actually want to last.
What I'm Actually Doing About It
I started thinking of sleep the way I think of money — as an account, not a mood. A bad night isn't a moral failure, but it is a withdrawal, and withdrawals need to get repaid on purpose, not by accident three weeks later when I finally crash.
I picked a bedtime and treated it like a flight departure. You don't negotiate with a runway. The plane leaves when it leaves. My body, it turns out, responds the same way to a fixed time as it does to a fixed schedule for anything else I actually take seriously.
I quit telling the five-hour story as a badge. Words shape belief. Every time I used to tell that story with pride, I was training myself to keep living it. I don't tell it that way anymore, and I've noticed I don't live it that way as often either.
I'm not chasing eight perfect hours every night — that's not realistic at this stage of life, with grandkids and travel and a body that wakes up on its own schedule some mornings. But I've stopped treating the debt as free. It was never free. It was just unbilled.
What's the sleep debt you've been carrying and calling discipline — and what would it cost to finally pay it down?
