I work in arbitrary blocks but analyze: should I experiment with different work rhythms? Map different rhythm options: Pomodoro, 90-minute cycles, half-day blocks. Calculate: which rhythm matches my natural focus capacity and task types? Show me the rhythm options: these patterns to test. Give me the experimentation protocol: try each for 2 weeks, measure productivity. Include: whether my current rhythm is optimal, what other patterns to try, and if finding my rhythm would improve consistency.
