4 — Mental Models

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.

Deliberate Practice

Practicing at the edge of current ability with immediate feedback — the specific structure that separates deliberate practice from mere repetition.

5 — Reading Technical Books

Reading dense technical material for retention and application rather than page-count completion.

Spaced Repetition

Reviewing material at increasing intervals timed to the forgetting curve, so review effort concentrates on what's about to be forgotten.
