What are you trying to do?

^ Agrees with comment above. I'm not too sure what you're trying to do? You talking about doing commentaries and LP's? I'm guessing that's what you meant.

If that's the case, then no matter how shy you are you have to jump into it.
If you are worried about people not liking your videos then start off small
Make some 2-3 minute small videos that no one will ever see, train yourself to be infront of the camera.

You know when you are playing off cam and you get involved with the game, you shout at it, and swear at the telly or the computer? You gotta train yourself to do that on cam.

My suggestion is to f*ck everything and just create a video If you think that you're good, not necessarily funny, but good ( look Cry ) then do your job. Do what you want to do. that's everything. And the hardest part, wait. Promote yourself on your facebook ( maybe the girl you like will watch this ), twitter, maybe some forums. And wait.

Nice sharing.Interesting.
