I have this as well. I worry about the system I'll use for doing things all the time. E.g. I now have a system for storing things I learn and getting back to them, and I've decided that the learning I do during work time should be some sort of project whereas during my own time I want to go wide and read on lots of random topics, from my Goodreads list. But the findings go into the same system. There is lots more to it.

I can understand "do something if you enjoy it, if you stop enjoying it then do something else." And my first reaction is to modify my system so that there are checks for enjoyment in there...

(In fact, I do. E.g. when working on to-do lists I don't prioritize them anymore unless necessary, I just try to think what I feel like doing the most. But I had to decide that).

It's like analysis paralysis but in many parts of life. There are things I'm very bad at because I never stop the analysis, like housekeeping.

I'm currently trying to find out if I'm on the autism spectrum, so maybe that is what is different about some people.
