Productivity glossary
20 terms you see everywhere, explained without jargon.
- Deep work
- Uninterrupted focused work.
- Cal Newport's concept: 60-120 minute blocks with no notifications, dedicated to deep thought. Rarer than shallow work, more valuable.
- Clarifying tasks
- Capture, clarify, organize, act.
- A simple system to get tasks out of your head and clearly decide the next action.
- Connected notes
- Ideas that connect with one another.
- Each idea becomes a simple note linked to others. Understanding emerges from connections, not filing.
- Cognitive load
- What your brain carries at once.
- Limited working memory capacity. Past 4-7 active items, quality collapses.
- Spaced repetition
- Recalls at the right interval.
- Reviews spaced out (1, 3, 7, 21 days). Beats passive highlighting.
- Pomodoro
- 25 minutes work, 5 minutes break.

- Popularized by Tiago Forte. Notes, PARA, CODE. Noctely is an active form of it.
- PARA
- Projects, Areas, Resources, Archives.
- Four-folder system by Tiago Forte. Universal across tools.
- Decision fatigue
- Exhaustion after too many choices.
- After 40-60 micro-decisions a day, quality collapses. Hence "decision burnout".

- Columns: to do / doing / done.
- Flow visualization. Caps work-in-progress to avoid saturation.
- Time-blocking
