Circadian Sprints: Structuring Your Day Around Peak Energy

Implementation Protocol
Determine Your Wake-Based Baseline
Alertness peaks roughly 2 to 4 hours after your natural wake time, followed by a post-lunch slump at 7 hours, and a late afternoon rise at 11 hours.
Schedule Your Deep Focus Sprint
Block out a 90-minute window during your morning peak (2-4 hours post-wake). Dedicate this block entirely to Task 1—your most complex cognitive commitment.
Protect Your Slump for Administrative Tasks
During your mid-day trough (7-9 hours post-wake), do not try to write code or compose copy. Use this time for low-friction tasks: email checks, code reviews, or billing.
Utilize the Evening Rise for Final Review
During your late afternoon alertness rise (11-12 hours post-wake), run your final tests, commit your code branches, or outline tomorrow's commitments.
Stop forcing focus during metabolic troughs. Structure your daily three goals to align with your internal biology.
Build routines that stick
Ditch the complicated todo boards. Download Pip to set exactly three morning commitments, seal them before 10 AM, and build streaks grounded in human biology.
