I've coached hundreds of people on their knowledge systems, and the pattern is always the same. ↓

They don't fail because their system is too simple. They fail because they built 47 tags, 12 databases, and a colour-coded status field for everything.

All you actually need is what I call a Minimum Viable Knowledge System where you just manage five things:

1. Tasks — what you need to do and when it's due

2. Projects — what you're working on and why it matters

3. People — who you work with and what you're doing together

4. Meetings — what was discussed and what was decided

5. Notes — your thinking, ideas, and reference material

The beauty of this is that you can use any tool that you like as long as AI can work with it.
