Parents do not think i will succed. What do i do?

I got a 91 average last year. Im in all of the top cles, however my parents still think i will amount to nothing. It used to not bother me, but now they keep on saying it and other things like, "what are you interested in? Cause i cant see anything your good at". I play cello in 2 youth orchestras, i play competitive soccer, and im 2 courses away from being a certified lifeguard. What should i do with my parents?
