Once I do that, I can sort them out better. I have an app called UpNote which works really well. For things with deadlines, I use ClickUp.
I personally think, after lots of experimentation, that getting ideas down and then organizing them into what can be done in the month/year works pretty well. A lot of ideas don't get done or don't make the cut but I realize that's probably for a good reason in a lot of cases.
For the latter, at the moment one piece of paper on my desk, and one vi-edited, networked-repository managed (so available on multiple machines) TODO.txt file. The odd shared spreadsheet (eg on Google Drive) for special projects.
Goals: high level and in my head. Fix the climate, see my kids through education, finish this PhD I started, pick up another start-up opportunity that passes by if not too much in conflict with the other goals.
