LESSON 1 · Master Your Time
Customize Your Intervals
The 25/5 ratio is a starting point, not a rule. Different work suits different intervals: creative work often flows better in 50-minute blocks with 10-minute breaks, while admin tasks may work best in 15-minute sprints.
Start with 25 minutes and notice when your focus naturally breaks. If you consistently zone out at 20 minutes, try 20/5. If you hit flow and the timer feels interruptive, try 45/10. Test for two weeks, and try to end each session while momentum is still high — it is far easier to restart work you stopped mid-flow. The goal is not 25 minutes; it is sustainable focus that matches the work.
