I have a stack of notebooks that goes back over two decades. Anything worth writing down goes in the notebook. No postits, scraps of paper or backs of envelopes unless I'm willing to throw the note away immediately. One of the things I learned in high school is that taking notes helps me to organize and remember my thoughts - even if I never look at the notes again. I don't refer to my notebooks much, but writing ideas down helps me triage ideas for things worth following up on.
