YouTube Channel

I love playing with makeup and have been wanting to start a YouTube channel for over a year but I never do because I'm just so scared and nervous that I'll sound dumb or something.. but I really think it's something I'd enjoy doing after I get over my fear of how I'll sound/look. Is there anyone else who wants to start a YouTube channel too but is too afraid?? Or is there anyone who does have one?? If so, how is it going for you??
