On the topic of hobbies…
I used to do Aikido (a Japanese martial art). When I started piano, I had been doing aikido for probably 7+ years. I had a black belt, I sometimes taught classes, and I met my husband through aikido, so we generally went to practice together etc.
After I started learning piano, at some point, I started to notice that as we would be leaving the house to go to the dojo, what I really wanted to do was stay home and practice the piano. I worked full time (then as now) and so time is always limited. Eventually, I was skipping more and more aikido practices for piano, and I decided to “take a break” from aikido. I never went to practice again after that.
I still work full time, so my free time is limited by that. Over the years, there have been other things I’d like to do, and other instruments I’d like to learn, but in the end, I always decide that piano takes priority and I realize I can’t pursue more than one hobby. I’m ok with that. The only thing I’ve managed to do with any consistency besides piano is make time for exercise, but I didn’t see that as a hobby so much as a health maintenance thing.
For those of you who are retired, I’ll let you all decide whether or how you can have more than one hobby.
But for those of us not retired, then there are many more restrictions on our time, and I think it’s ok to just pick one hobby.
Or if you can make it work with your schedule, have more than one hobby and be ok with possibly slower progress but more activities.
I think your heart tells you how you want to be spending your time. Mine did, and does.
