The plan that assumes a skill you don't reliably have
Most planning advice is built on an assumption: that you can look at a task and estimate, reasonably accurately, how long it will take and when to start it. Research on ADHD and time processing points to consistent, moderate difficulty across exactly that kind of estimation — across dozens of studies and several different task types, not one narrow test.
A plan built on time estimates is a plan built on the one input that's least reliable. That's not a reason to give up on planning. It's a reason to plan differently.
Anchor to events, not clock times
An anchor is something concrete and observable — a thing that has already happened — rather than a number you have to track and interpret in real time.
"After breakfast" is an anchor. "At 8:15" is an estimate wearing a clock-time costume, and it depends on the same unreliable tracking as everything else.
A day built on anchors instead of estimates might look like:
- Wake → first anchor is a completed action, like a shower or a specific drink, not a time on a clock.
- Transitions triggered by the previous thing ending, not by checking the time and deciding it's probably time to move on.
- Buffers built into the anchor itself — "start getting ready when the coffee's made," not "start getting ready at 8am," because the coffee doesn't need you to correctly perceive elapsed time.
Why this holds up on bad days
Estimate-based schedules fail quietly: you're not late until you suddenly are, because nothing flagged the drift along the way. Anchor-based schedules fail loudly and early, because a missed anchor is obvious the moment it's missed — the coffee's cold, the shower never happened — which gives you a chance to course-correct before the whole morning is gone.
This isn't about becoming more disciplined. It's about building a system that doesn't depend on a kind of time-tracking that the research says is genuinely harder to do reliably.
