As a serial hobbyist and jack of all trades, I can relate. There's always a million things I want to do and little time to ever do them. I often find myself jumping into whatever thing interests me the most in a given moment, usually meaning I spend a lot of time chasing the novelty of a new interest rather than pushing through the next level of an existing one.

In the course "Time Management for Mortals" by Oliver Burkeman, he asks "What AREN'T you going to do with your life?". You're going to die someday and you only have a limited amount of time before that happens. The trick isn't finding out how to fit all the things you want to do into your life, it's realizing that not everything fits and deciding which of the things you want to do aren't going to make the cut.

That question and the associated lesson have helped me focus more on my core set of interests rather than frequently investing time into new or lower priority ones. Maybe that could help you as well. Don't just ask yourself whether you want to learn something, but ask if it's something you want to learn badly enough that you're OK with it taking the place of anything else you could be doing with your time
