The 25-minute block: how to actually start

Starting is the hard part. A short timer, a single task and a visible finish line get you past it.

Nobody procrastinates on studying because they are lazy. They procrastinate because the task in their head is "study for calculus", which has no start, no end and no way to know if it is going well. The fix is to make the task tiny and concrete: one section, one timer, one goal.

The block

1. Pick one task you can finish in 25 minutes: "ten questions on the chain rule", not "review derivatives".
2. Phone in another room, or face down and silent. Every notification costs you about ten minutes of re-focus.
3. Start the timer in the Focus room and do nothing else until it rings. If you finish early, do the next five questions.
4. Five-minute break, standing up. Then another block or done for the day. Two real blocks beat four fake hours.

When you cannot start

• Make the task even smaller: "open the practice page and do one question". Momentum does the rest.
• Tell yourself you only have to do five minutes. You are allowed to stop after five; you almost never will.
• Put the block on the calendar at a fixed time. Decisions made in the moment go to the phone.
• Study next to someone who is also studying, in the library or at a Mathub study session. Social pressure is a tool.

Longer blocks

Once 25-minute blocks are easy, try 50 with a ten-minute break, which suits problem sets that need a warm-up. Ninety minutes is the ceiling for most people; after that quality drops faster than you notice. The Focus room logs every session, and the minutes count toward your streak, quests and XP.
