# Second Brain

A personal knowledge base for **building understanding that compounds over time**. Not a note dump - a structured system for capturing knowledge you can actually retrieve and use.

## Philosophy

Your second brain should:
- **Capture understanding, not just facts** - Write for your future self who forgot the context
- **Be retrievable** - Structured so you can find things when you need them
- **Stay evergreen** - No private details, credentials, or time-sensitive data
- **Reflect real experience** - Only save what you've actually learned or used

Before saving: *Will future-me thank me for this?*
