[tyrfing]

I keep it very simple. A big text file (with markdown syntax highlighting these days) in something that is almost an append-only format, mimicking a paper journal but taking advantage of editing/insertion capabilities. Each Sunday I add the upcoming days of the week at the bottom, fleshing out a basic plan of what's happening. Each day I note down what got done and move things around, planning for upcoming days. The 'anchor' reminder is keeping track of my sleep, which has been a terrific help for sleeping properly. Around monthly I'll build a "todo list", an awful lot of which will never get done, and between weekly chunks I have bigger blocks of writing on just about anything.

I've never had success with the systems and apps that require maintenance, there's just too much cognitive burden in reviewing and cleaning them. It's much easier for me to just rewrite from scratch, maybe copying a few items, and then accept I can ctrl+f a previous month if necessary.
