I tried many times to "go digital" at work, using different apps and methods, but it comes down to 3 things: I take notes and jot down ideas nonlinearly. For example, I'll start taking a note from a meeting or lecture, then have an idea that I'll jot down elsewhere, but go back to the original note to finish it then go and complete the idea. It's stupid, but it works for me. The second is that I infrequently need to review my notes that are written since they get committed to memory. Unfinished ideas are different. Third, I can find notes faster when I wrote them vs typed them. I have a photographic memory. My desk is a huge mess, but I can usually find what I need because I remember it's physical location in the pile.
