I think becoming proficient in some form of artistic expression is very helpful for achieving self-actualization.

My biggest frustration, currently, is a lack of time and energy to devote to my creative projects. I still give them some time, but between a full-time job, child care, and other day-to-day responsibilities, it is not as much as I would like.

My wildest hope for society in my lifetime is that we will experience dramaticly shorter work weeks. Keynes predicted 15 hour work weeks by 2030 or so. If I could afford a modest life on only 15 hours of labor, and devote other time to family, friends, and art, I would feel so amazing. I'm skeptical of the claims of AI, but a society where a shorter work week is the norm would turn me into its biggest fan.

Anyway, despite my frustration, the time I spend with my creative projects results in my greatest self-satisfaction, after the time I devote to raising my children. And the creative outlets I pursue today are directly related to the artistic skills I developed in my youth (including music). So yeah, it probably won't pay the bills, but there's much more important things in life than bills.
