Personal intervention map · September 2026
Everything is downstream of sleep.
The original chart plots how many strangers rated a thing against how often they called it life-changing. That’s a popularity map. This one is mine: friction to actually do it against expected payoff for a 40-something single dad of four who runs ultras, sits in dashboards all day, and is trying to hold 11pm → 6am through a divorce. The top-left corner is where the leverage lives. Nothing in the supplement aisle beats the four things sitting up there.
Friction against payoff
InteractiveEvery intervention I have looked at seriously, scored on how hard it is to actually do and how much I expect it to move energy, mood, and focus. Hover a point for the reasoning. Click a category to hide it.
Scores are my read of the evidence weighted for my situation — a prioritization, not measured effect sizes. The shaded corner is the cheap-and-it-works quadrant.
The next five
In this orderDo these in this order — each one earns the next.
Move lights-out to 10:30pm
You’re running a 7-hour target through a divorce, four kids, and a 300-person sales org. Seven is a floor, not a target. The half hour you’re missing is the same half hour that would fix the afternoon crash you’re considering modafinil for.
First moveSet a 10:00pm alarm labelled “wind down”. Not a bedtime — a start-stopping time. Four weeks.
Bright light in the eyes by 6:15am
The 10:30 bedtime won’t hold unless the clock it’s attached to is anchored. Ten minutes outside — porch, driveway, the first block of a run — does more for sleep onset than any pill in the bottom half of this chart.
First moveAttach it to something you already do. Coffee happens outside now.
Last caffeine at noon
Six-hour half-life. The 3pm cup is still a quarter-dose in your blood at 11pm, thinning exactly the deep sleep the first two rows are trying to buy.
First moveNothing to buy, nothing to build. Just a hard line on the clock.
Two strength sessions a week
You’re an aerobically fit man with no resistance training, which is the classic ultrarunner gap — and it’s the piece that protects your running from the injury that would take the whole base away.
First moveTwo 45-minute sessions on Dad nights after the kids are down. Squat, hinge, push, pull, carry. No program-shopping.
Book a physical with full bloodwork
Ferritin, B12, thyroid, testosterone, A1c — plus an honest conversation about sleep and snoring. One appointment either finds something specific or clears the whole doctor-gated column off this chart.
First moveBook it this week. It’s a fifteen-minute phone call you’ve been postponing, and it’s the only item here you can finish today.
Already in the stack
Don’t touch itThis is a good base. The running and the meditation are the two heaviest-hitting things on the whole chart and I already have both. Creatine, D3, and fish oil are cheap insurance. Resist the urge to optimize this half — it’s working.
Where I’d waste six months
The overbuild trapThe bottom-right of the chart is a research project disguised as self-improvement: racetams, adaptogens, exotic diets, stacking protocols. High friction, near-zero evidence, endless reading. It is exactly the kind of thing that feels like progress. The whole grey cloud down there is worth less, combined, than moving lights-out thirty minutes earlier.
One honest experiment at a time: pick one row from the list, run it four weeks, note energy and mood on a 1–5 in the Sunday review. That’s the whole protocol. Don’t build a tracker for it.
