When you don't need to share information, there's nothing better than a notebook to see all of your ideas spread out and iterated. No need to log into anything. Take it with you anywhere -- sit on a bench and ideate. Go to the gym and jot down ideas.
I can keep my daily goals in a checklist in there and just check them off 1 by 1. No need for GitHub projects or anything like that because there's no need to communicate status with anyone.
Well, some sort of log, be it paper or a text file of whatever works for you.
Keeping track of the decisions you make, both to do things and to NOT DO THINGS (and why) is almost a superpower. You can save so much time when you come up with a 'new but vaguely familiar' idea by being able to check back through your notes and see what you came up with last time it occurred to you. Maybe circumstances changed, maybe they haven't, but you can bring yourself back up to speed on what you've done previously with little effort.
I retired fairly recently and I seem to have largely gone back to a Moleskin weekly calendar and a couple of notebooks. (I do try to avoid too many random pieces of paper.) For more detailed tracking for dev (etc.), I could see using GitHub or something along those lines but paper works pretty well as long as you don't need to share.
I tried to differentiate mine a lot, but I often found I had the "wrong" notebook at the "wrong" times. Now I have have a general notebook, and other notebooks that might live in 1 place. E.g. all my D&D campaign notebooks sit with my D&D stuff.
But I don't have a separate work/life/personal dev notebook. Shuffling them got annoying.
Nothing nearly systematic enough. I do use some back of calendar pages for simple stuff. And small separate notebooks for specific projects. But I found a few books were better than an electronic thing for most purposes for an individual.
