If you didn't have to worry about the cost what would you like for a hobby?

If I had enough money that I didn't need to work anymore, I would like to get back to playing the piano and practice for hours each day so I could get back to the skill level that I was at in high school, and once I learned enough, maybe I could entertain people in nursing homes or other places where people could use some entertainment. If I had enough money, I could just play for free, just for the joy of playing and bringing joy to others.
