Pursuing My Dreams

"If your dreams don't scare you, they aren't worth having". My thoughts and dreams right now are kinda scaring me. I'm thinking long and hard about what I want to do with my life - I really want to think about being on radio. Radio is something I've grown up with, and I've kind of always wanted to be a radio DJ. I don't have any ideas about what that job entails, though. What kind of things would I get to do?
