I agree with @Mischief Izzy: Go for it! :) You shouldn't hold back because of what others might think and say. If you are interested and want to do it, then so be it! ^^
I say go for it, I was worried at first when I started my idea of being a film reviewer, I was worried that I would be mocked. But I'm happy I decided to make my channel. So as fellow YouTuber I say go for it.
