I see a ton of recommendations that invite you to blurt out all your thoughts and capture them, but after you do that for a while... what tools/processes help you know what you can delete or let go of? I have kind of a home-grown anti-todo list system that is hooked up to my life principles, such that if an "oh, I should do this" idea doesn't actually line up with them, I just don't add it to the list. But that's pretty manual and home-grown. I don't know, it's just that the "capture every thought" genre of software was attractive in my 20s, but after a point it just gets overwhelming.
