safe bet: long term investment for retirement or to buy a house.

dreamer me: study the piano bachelor you always said you wanted to do, even if it's just the bachelor, and not a master, even if you're doing it not for the money or fame, but just because you want to play and maybe teach part time, but mostly because is something I enjoy doing, even if teaching the piano is mostly a side job to my main job.

I don't know what to do. Feel free to read my previous post, because it's related to this one.
