Should I ???

I am thinking of making a YouTube channel but keep on having second thoughts ... Some shots make me look ugly, what about all the people that won't like it and judge plus the fact that I don't have a camera but I do think it will be fun. What should I do? Plus I'm not sure on the topics I should do it on, I'm thinking on beauty, makeup reviews and vlogs. I'm also scared of being unsuccessful... Like with nobody that watches it.
