Identity-Based Habits

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.

Habit Stacking

Anchoring a new habit to an existing routine so the trigger is already reliably in place, instead of relying on remembering.

Breaking Bad Habits

Inverting the habit loop — making the cue invisible, the response unattractive, or friction high enough — to dismantle a behavior deliberately.

Consistency Systems

The streak and accountability mechanisms that keep a new habit alive past the initial burst of motivation.

4 — Environment Design

Shaping the physical and digital environment so the desired behavior is the path of least resistance, and the unwanted one requires deliberate effort.
