It really has a lot to do with how you feel about yourself. The more you criticize yourself, the more you fear that others will do the same. I've made 10 videos and I'm still nervous when I'm about to film because my mind starts going "you're awful, you're ugly, [every insult known to man]..." and then I have to say "Mind, stop it, you're talking BS."
Same goes for other people finding out. If you love what you're doing, it doesn't matter what others will think. I had one person finding out and they called my videos silly, and I thought yeah they might be a little silly if you think about it, but I loved making them and I'm proud that I did.
