Not really a solution, but a problem that I have (which this thread has actually given me several new ideas to try fixing) isn't so much organizing or tracking my goals, it's that even when I get them organized, and plan out my days (not excessively, but a handful of easily achievable things I want to do in a day or week) I find that I don't have the drive or motivation to accomplish them half the time.
Getting home from work exhausted, not from stress exactly, but from just being focused and working for the whole day + commuting + going to the gym, makes it hard to find the energy to do the things I WANT to do. So I end up going for the easy thing, which is browsing HN or Reddit, watching TV, playing video games. I do enjoy those things, but feel like I waste time when I do them.
I have realized in the past several months the very common idea that getting started is the hardest part. Most of the time when I force myself to just start on something, I end up investing hours into it.
The other problem is that I want to do too many things, and often don't want to start on a side project, or practicing an instrument, because I don't want to do just one thing for the night and neglect other things, which leads to just doing nothing of value that I wanted to do.
I just try to constantly remind myself that if I spend an entire night practicing keyboard, it's a thousand times better than thinking about the things I want to do, and then browsing the internet all night.
To the original topic though: I use a combination of Keep, OneNote, and a Habit tracker to help. It's just the breaking through and starting on things that is the main issue for me. Thinking of trying out a kanban board to track personal goals though.
