That sounds like the difference between the J and P traits in the MBTI system. J-types (judgers) like me (and probably you) tend to plan ahead a lot and like to have matters settled, whereas P-types (perceptors) prefer to keep decisions open and decide how to do stuff when the time comes to act. I would guess that pmarreck is a P-type, or would at least lean towards P.
Wikipedia has more details on MBTI, and there are online self-tests for your own MBTI classification.
Disclaimer: Note the "Criticism" part of the Wikipedia page. MBTI is AFAIK not a tool that professional psychologists would use. Nonetheless, I find it useful in order to find similar people on the internet. For example, if I want to learn a new skill, a search query like "[thing] tutorial for INTJ" gives me way better results than just "[thing] tutorial" because I get recommendations from people who think in similar ways.
Basically I am able to (mentally and physically) walk away from work and let go of it and go home and game or work out or whatever. Then, the next day when I sit down again, I get my bearings and see where I'm at and then proceed!
There are a few exceptions to this, of course, but it's always with hard problems I become absolutely OBSESSED about. For example I couldn't find an XML parser in Elixir a couple weeks ago that I liked, so I was faced with writing my own... which I did... and then released as open source https://github.com/pmarreck/mega_xml but I was literally up until 4:30AM one night figuring out how to turn an event-based XML parser callback mechanism into an Elixir Map datastructure (something I had never had to do before, but which I somehow knew I was barely capable of figuring out, lol). It was extra tricky (for me) due to the lack of mutability
