I agree with everything except your example of playing instruments. How is that a waste of time? It takes years to master an instrument, so if you ever want to be good at it, it's a very good use of time. Secondly, it's not easy. So sticking though with it teaches you self discipline. I know a lot of adults and kids who do it willingly. Myself included. The reason we do it willingly is because at some point we were forced to learn how to play music and we stuck with it for a few years; after all that time we got good at playing instruments, and started enjoying it. It also became much easier to learn new instruments and songs, boosting the enjoyment. But we would never have reached this point if we weren't forced to drudge through the years of hard work.
