Hi Tommy, You don't need a particular degree to achieve Youtube fame but you have to have an expertise that are interesting to many people. Did you know Adele got her start on Youtube? If you want to sing on youtube then focus on your music skills. If you want to do funny science experiments on youtube, then take science courses at school. Ask yourself, "what do I most like to watch on youtube and what do I need to be able to do this?" It sounds like you might want to be a performer? Maybe join the school choir or try out for a play?
I'll be seeing you on youtube!
