This is what I've been doing for a while, with good results. Step one: get it out of my head. Short reminder sentence in e-mail to myself, or google keep, napkin whatever. Step two: get it out of my head. Periodically (same day, same week) I triage these notes into a single continuously growing brain dump google doc, or a dedicated google doc per subject in a folder if its warranted. Before I often stressed when I couldn't recall something I knew was important or had been a cool idea. Now I still don't have time to explore 90% of the things I think about, but I don't stress about it.
