# Second Brain

## Overview

A second brain is an external, organized, searchable system holding what your biological brain shouldn't have to: notes, ideas, resources, tasks, references.

Purpose: free your mind for thinking by trusting capture; make knowledge compound by connecting and revisiting it.

Built on four capabilities: capture everything, organize for action, distill to essence, express by creating.

Tool-agnostic — Notion, Obsidian, or any notes app works. The system matters, not the software.
