90-minute exam revision session with forest at dusk and a timer, if you are tired of apps

Sit down, press start, and test yourself for 90 minutes. One full ultradian cycle, for work that needs a long runway.

90:00

Press start. The timer keeps time so you do not have to look at a clock.

Turn your phone face down if it's within reach. If it's in another room, even better. No account, no streak, no notification asking how you feel. This is a short one, so let's use the time properly.

1 Before you start

  • Have a piece of paper beside you for the thoughts that will try to interrupt.
  • Decide in advance that a bad sentence is still progress.
  • Clear the surface in front of you down to the thing you are working on.
  • Decide what you will do if you get stuck: write the problem out, then move on.
  • Write down the one thing you are going to do, in a single sentence, before you start.

2 While the timer runs

  • If your attention keeps sliding, shorten the next block rather than abandoning this one.
  • If nothing is working, write badly on purpose for two minutes.
  • When you get an idea for something else, park it. Do not follow it.
  • When you finish a piece, pause for three seconds before starting the next. It keeps the pace honest.

3 When it ends

  • Put the notes you made where you will find them next time.
  • Have a drink of water before you check anything.
  • Decide whether the next block is the same task or a different one. Do not drift into it.

4What to put on

forest at dusk — Birds settling, leaves moving, nothing sudden. It works because it sounds like a place you can safely ignore.
