You've been told to start small. You did. You decided to "just" journal for ten minutes, "just" do a fifteen-minute tidy, "just" go for a short run. And within a week or two it collapsed anyway, and you added one more piece of evidence to the pile labeled I can't stick to anything.
Here's the uncomfortable truth most advice skips: for an ADHD brain, "small" is usually still too big. Ten minutes of journaling is not small — it requires you to start, sustain attention, and resist the seventeen more interesting things your brain offers in the meantime. The problem was never your willpower. It was the size of the ask.
Why tiny beats small
There's a real model behind this. Behavior scientist BJ Fogg describes any behavior as the product of three things happening at once: motivation, ability, and a prompt. Motivation is the least reliable of the three — it spikes and crashes, and ADHD brains feel that swing harder than most. So you can't build a habit on motivation. You build it on ability: you shrink the behavior until it's so easy you can do it on your worst, most depleted, most distracted day.
James Clear calls a related version of this the two-minute rule — scale any new habit down to something that takes two minutes or less to begin. "Read before bed" becomes "read one page." "Do yoga" becomes "put my mat on the floor." The point isn't to do only two minutes forever. The point is to master the art of showing up, because a habit you actually do is infinitely more powerful than the impressive one you keep abandoning.
A habit has to exist before it can grow. You can't optimize a behavior you're not doing. Tiny first, bigger later — never the other way around.
Find the version you literally cannot fail
This is the move. Take the change you want and keep shrinking it until your honest reaction is, that's so small it's almost stupid. That feeling is the target, not a sign you've gone too far.
- "Drink more water" → fill one glass and put it on your desk.
- "Clean the kitchen" → put one dish in the dishwasher.
- "Start exercising" → put on your running shoes and stand up.
- "Floss" → floss one tooth.
Yes, one tooth. The goal isn't dental coverage — it's becoming a person who flosses, and that identity is built by the act of starting, repeated, not by the duration of any single session.
If you can imagine yourself skipping it on a bad day, it's still too big. Shrink it again.
Anchor it to something you already do
A tiny behavior with no cue just floats away. So bolt the new thing onto an old thing that already happens reliably. Fogg calls this an anchor; the formula is "after I [existing habit], I will [tiny new habit]."
- After I start the coffee maker, I take my meds.
- After I sit down at my desk, I write one sentence.
- After I brush my teeth, I do one push-up.
The existing habit becomes the alarm clock you don't have to remember. You're not asking your brain to generate the prompt — you're borrowing one it already fires.
Let yourself stop at tiny
Here's where ADHD brains often sabotage a good system: you do the one push-up, feel a flicker of momentum, do thirty, glory in it for three days, then crash and quit. The intensity is the relapse trigger.
So make a quiet rule: the tiny version always counts as a win. Some days you'll do the one page and naturally keep going — wonderful, that's a bonus, not the standard. Other days the one page is the whole thing, and you still get to mark it done. You're protecting the streak of showing up, not chasing a daily peak you can't sustain.
Celebrate it like it mattered
This part feels silly and it's the part that works. Fogg's research points to emotion, not repetition, as what actually wires a habit in. Right after you do the tiny thing, give yourself a genuine flicker of yes — a fist pump, a quiet "nice," a smile. You're telling your brain that felt good, which is exactly the signal it needs to want to do it again. (None of this replaces medical care; if low motivation runs deeper than habits, it's worth talking to a provider.)
The reason "small changes" failed you before wasn't that you aimed too low. It's that you didn't aim low enough, and you forgot to make showing up the entire goal.
If the hard part is remembering the anchor, marking the tiny win, and noticing the streak quietly building, that's exactly the kind of externalizing NoPlex is built for — so the system holds the structure, and you just have to do the one push-up.
