> Have a very lightweight note taking mechanism and use it as much as possible... Don't try to make these notes good enough to share as that adds too much overhead.

Second this. I use sublime text almost exclusively for this purpose. I have one file called daily_notes.md that has everything from meeting notes to formal writing to pasted error messages and code.

Each day gets an h1 but that is the extent of formal organization. I’m actually decently organized (at work, at least) but the simplicity is all about lowering the overhead of jotting stuff down. Keeping everything in one doc makes for very easy search.

Otherwise, I try to write reminders right away with whatever is handy. Mainly: Post-its, slack reminders, and Gmail scheduled sends to myself.
