Timeboxing Planner

Three timeboxes, honest durations, and a planning-fallacy check — the ADHD-friendly way to plan a day that actually finishes when you think it will. Print one per day.

1

Pick 3 tasks that matter today. Not everything — just the three that would make the day a win. If choosing feels hard, run them through the Decision Matrix first.

2

Estimate each one honestly. Write down what it took last time you did it, then multiply by 1.5 for the buffer. ADHD brains underestimate by ~40% — the buffer is not optional, it's the plan.

3

Run the box. Start a Visual Timer and work until the buzzer. When the box ends, you stop — done or not. Rebox what's left instead of bleeding into the next block.

Today's Timeboxes

Date: ______________________  ·  Day starts: ________

Timebox 1
The one task (not a list — one thing)
Start → Finish
What "done" looks like
Timebox 2
The one task (not a list — one thing)
Start → Finish
What "done" looks like
Timebox 3
The one task (not a list — one thing)
Start → Finish
What "done" looks like

Planning Fallacy Check

Before you commit, be honest: last time this took ________  ×  1.5 = new estimate ________. If the new estimate doesn't fit your day, cut scope — don't cut the buffer. Prefer a digital version? The free Timebox Planner tool bakes this in automatically and shows your honest finish time.

Time Blindness Rescue Rules

When the plan wobbles (it will), these three rules get you back on track:

Stop at the buzzer. The box is the commitment — not the task. Done or not, the box ends.
Rebox, don't bleed. Overflow goes into a new box later, never into the next block.
Can't start? Do 2 minutes. Start a 2-minute timer and do the tiniest version of the task. Momentum beats motivation.
