How do I apply the idea that the commitment to capacity ratio?

The most direct way to practice is through a focused exercise: Open a blank document. List every active commitment you hold right now — professional, personal, social, household, health, learning, creative. For each one, estimate the weekly hours it realistically requires, then add 30% (this corrects for the planning fallacy — you will resist this adjustment, do it anyway). Sum the total. Divide by your measured weekly capacity from L-0962 (if you skipped that lesson, use 35 hours as a conservative default). Write the ratio. If it is above 1.0, circle it in red. You are currently overcommitted by a mathematically precise amount, and no productivity system can fix it. Something must be cut, deferred, or delegated. Pick one commitment to remove or reduce this week.

Common pitfall: Calculating the ratio once, feeling alarmed, and then continuing to say yes to new commitments without updating the number. The ratio is not a one-time diagnostic — it is a running metric. Every new commitment changes the numerator. Every illness, life event, or seasonal shift changes the denominator. If you treat this as a snapshot instead of a dashboard, you will drift back above 1.0 within weeks and wonder why you feel overwhelmed again despite having "done the exercise."

This practice connects to Phase 49 (Capacity Planning) — building it as a repeatable habit compounds over time.
