3 — Building Self-Discipline

Productivity for Knowledge Workers

A book-shaped table of contents for productivity as practiced by a knowledge worker: foundations, self-management, goal setting, time and deep work, personal knowledge management, learning, task systems, decision making, habits, digital productivity, engineering and career practice, health, review, and an advanced operating-system layer, plus reference appendices — cross-linking existing notes instead of duplicating them.

Energy Management

Physical and mental energy as the actual constraint on a day's output — capacity fluctuates on a rhythm, not a flat 8-hour line.

Motivation and Momentum

Why the first small action matters more than the plan — momentum is generated by starting, not felt before it.

Attention Management

Attention as a separate, spendable resource from energy — where it leaks by default, and how to budget it deliberately.

Decision Fatigue

Every decision draws down the same finite pool of willpower — reducing trivial daily decisions protects capacity for the ones that matter.
