SHOULD I FOLLOW MY DREAM?

i have this dream, since i was 3 i wanted to be a singer.I LOVE tO sing. i would get in trouble at times in school for writing a song when i should have been doing cl work, and when all the other kids play on the swings at recess i would be writing and singing. im 17 now and it about time for me to go to college i am a honor roll student and i understand that college is very demanding. i don't want to have to give up my dream tho because i am truly talented and i put to much into it but i know school is not an option it's a must...I DON'T KNOW WHAT TO DO!!!
