Timeboxing: Put Tasks in Your Calendar, Not Just on a List

TTobias Tröndle · Updated: 2026-03-25

A list tells you WHAT, but never WHEN. Timeboxing answers both: every important task gets a fixed slot in your calendar — like a meeting with yourself.

How it works

  1. Pick the 2–3 most important tasks of the day.
  2. Block out realistic slots ("9:00–10:30 proposal") — buffer included.
  3. Treat the block like an appointment with your boss: it doesn't just get pushed around.

Why it works

  • Parkinson's Law: work expands to fill the time available. A box limits it.
  • No more "later": later now has a specific time.
  • Reality check: if your to-dos don't fit in your calendar, you've got too many — timeboxing makes that obvious right away.

Finding the balance

Don't schedule your whole day: box 60%, leave 40% free for the unexpected. What belongs in your calendar vs. your list is covered in this article.
