What is Building a Second Brain (BASB/PARA)?

Tiago Forte's personal knowledge management system. Instead of trying to remember everything, externalize your thinking into a 'second brain' organized by actionability, not topic. The PARA method (Projects, Areas, Resources, Archives) ensures every piece of saved information has a clear purpose.

Is there evidence for it?

How do you do Building a Second Brain (BASB/PARA)?

  1. 1.Choose one digital tool as your second brain (Notion, Obsidian, Roam, Apple Notes) — the tool matters less than the system
  2. 2.Organize everything into PARA: Projects (active with deadlines), Areas (ongoing responsibilities), Resources (topics of interest), Archives (completed/inactive)
  3. 3.Capture ideas using the CODE workflow: Capture what resonates, Organize by actionability, Distill to essential points, Express by creating something new
  4. 4.Apply 'progressive summarization': bold key passages, highlight the boldest, write a brief summary at the top. Each layer makes retrieval faster
  5. 5.Review and maintain weekly — move completed projects to Archives, ensure active projects have recent notes

How long does it take?

4-6 hours initial setup, 15-30 minutes daily maintenance.

Is it hard to start?

medium.
