I try to keep as much in my head as possible.

Stuff in my head is always easy to change, and I find I need to change CONSTANTLY.

I create what I term a "napkin sketch," and try not to write down too much, afterwards.

Documentation is a HEAVY "concrete galosh."

That said, it's often imperative to write stuff down; especially in a team. It's just that every single thing you write down becomes tech debt.

I talk about that here: https://medium.com/@ChrisMarshallNY/concrete-galoshes-a5798a...
