What does it mean that the commitment budget?

You have a limited capacity for active commitments — track them like a budget.

Example: You are holding seventeen active commitments. You know this because you just counted. Three professional projects with weekly deliverables. A daily exercise routine. A meditation practice. A journaling habit. Learning Spanish on Tuesdays and Thursdays. Reading one book a month. Calling your parents every Sunday. Mentoring a junior colleague. Writing a newsletter. Volunteering for a nonprofit board. Meal-prepping on Sundays. Reviewing your finances weekly. Maintaining your personal website. Keeping your inbox at zero. Practicing guitar. Each one, in isolation, is reasonable. Each one has a good reason behind it. And yet you are failing at most of them — not because any single commitment is too hard, but because seventeen simultaneous commitments exceed your capacity the way seventeen simultaneous credit card payments can exceed your income. You are commitment-bankrupt, and you got there one reasonable yes at a time.

Try this: Conduct a full commitment audit. List every active commitment you are currently holding — professional, personal, creative, health, social, domestic. Include the ones you have been quietly failing at. For each commitment, estimate the weekly time cost (in hours) and the weekly cognitive cost (rate 1-5 for how much mental bandwidth it occupies even when you are not actively working on it). Sum both columns. Now compare your total time cost against your actual available discretionary hours per week, and your total cognitive cost against a budget of roughly 15-20 points (representing a realistic cognitive load ceiling). If you are over budget — and you almost certainly are — identify the two or three commitments with the worst ratio of importance to cost and mark them for renegotiation, deferral, or elimination.
