Do you hobbies that can put you at risk? Why?

Yes, my hobbies sometimes put me at risk. My hobbies can interrupt to do my priorities as a student or a worker. When I was a high school student, I enthusiastically joined my music band every day, spending a lot of time practicing the instrument I played at home and meeting band members once or twice a week. Even though I enjoyed that time and gained contentment from playing the piano, I sometimes suppose if I spent more time studying instead of joining the band. In this regard, I have been learning how to prioritize between what I have to do and what I like to do. To be specific, I need to organize my schedule and time effectively and efficiently doing something based on its importance.
