I've been using a bullet journal inspired system for a while now. Picked up the numbered pages, mostly sticking to one topic per page and maintaining the index for the particularly interesting pages. Also there's the note-taking tic of writing everything as single-line bullet points which makes it easier to do quick stream-of-consciousness capture. The notebook is filled chronologically, each page gets a date marked on the margin. The note pages are useful for thinking aloud about problems even if I never read them again later. Instead of the planning calendar, I've got a daily done things calendar. Each month gets a dedicated page, and the page gets a one-line summary of what I accomplished that day. This builds up a long-term log of what I've been doing with minimal daily effort. Didn't really figure out the more complex calendar systems in bullet journal and I use a digital calendar to track appointments. The journal is more of a thinking tool than a time management tool. The final bit is TODO lists inspired by the autofocus system. All active TODO items must live on a single notebook page. Once the page is full, open items must either be abandoned or migrated to the next TODO page. This keeps the list from going stale and works very well with analog notebook pages. I can get an immediate view of the current work situation by just looking at the live TODO page.
