My advice to anyone, is to start tracking stuff on paper, and once you've got some workflow nailed down, search for digital tools to augment it (or be fine with the current workflow). I prefer digital and have settled on org mode. It has the structure that I would need to implement if I was starting with .txt files.

Another tool I like is Things.app. But it's Apple only and I'm moving away from that ecosystem.
