I want to get somewhere with my life...?

hey :) ur not even thirteen yet, u hv ur whole life ahead of u and with tht kind of determination u will definetly get somewhere. I play the violin too and i suggest learning some famous rock or pop songs with violin in them or try the electric violin if ur a gud enough violin player. And it's not too late to learn guitar: i play piano, violin and guitar and i started guitar at 13. So don't give up on that and keep playing violin. You have it in you to be a famous musician :D
