In the beginning, your struggle is not to make a great video. It's to make videos at all and be ok with them being public. So your goal shouldn't be "must make a fantastic first video" your goal should be "Must get the guts to put something up on youtube". It took me like... over 100 videos to get to where I could consistently deliver content I was truly pleased with, up until then I was just a little more pleased each time, now I'm still trying to get to where I feel I am NAILING my videos and they are at the highest level I can get them. I've gone from "embarassed of all my uploads" to "this is good enough I'm ok with this" to "Ok I can really see the appeal of my videos I'm doing well" to now hopefully getting to where I'm like "omg I am ecstatic to put this out I NAILED it". I have yet to make it to step 4, vlogging is a process.
