I'm a serial hobbyist. Two of the newest ones are 3d printing (making objects for around the house with an Ender3) and piano (played guitar before but never learned theory, about six months ago I began to climb the mountain that is jazz improvisation)
Nice! Jazz bassist here. One thing about I like about jazz is that no matter how much time I put into it there is always some way to improve and some way to get better at it. Even the folks that I play with that are substantially more gifted at jazz vocabulary are consistently working to hone their craft.
I really should seek out others to play with but it just doesn't seem like there's enough hours in the day to practice for myself, let alone to organize jam sessions
Finding time to practice is tough! I am fortunate that I work 30 hours per week and can make time to practice for at least 30 minutes to an hour on most days. When time is tight I do things like practice electric bass in the kitchen while I am waiting for water to boil / food to cool / etc.
When I worked 40 hours per week often I didn't have energy to practice most days.
