The best thing I have done to keep the buckets and remember stuff:

- I write everything down that comes to my mind, immediately

- I keep a Trello board with 5-6 lists, 1 for work, 1 for private stuff, 1 for side-projects, 1 for books I’m planing to read. Only rule: it has to fit on a screen

- when working, I try to move away from the laptop as often as I can, I print things out and read them offline, make notes etc.
