3 — Progressive Summarization

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.

Second Brain

Externalizing capture and organization into a trusted system so working memory is freed for actual thinking.

Zettelkasten

A densely linked slip-box of notes where structure and new ideas emerge from the network of connections instead of being decided upfront.

Building Knowledge Graphs

Turning atomic notes into a retrievable network through deliberate cross-linking — the same [[wikilink]] and backlink mechanics this wiki runs on.

5 — Reviewing Knowledge

A deliberate resurfacing cadence for captured notes, separate from spaced repetition of facts, that keeps a growing knowledge base connected instead of write-only.
