Well if the big thing that is holding you back is the fear of judgement or people thinking you might have come across in a negative, then you should absolutely post it. We should all be conscious of ourselves, the outward expression of the things we do, and the way the world views us- but it should never control us to point point where we are scared to express ourselves or show our faces simply because someone may think we are less than perfect. There is a pretty solid chance that you are thinking about it WAY more than someone else is, and most likely they are too busy being scared of what you think of THEM!
Just take the leap my dude. Even in the off chance that you come across awkward or rude, nobody here is going to spend the rest of their lives judging you or even thinking about how you were in the video. We all have WAY too much going on to think about one little moment that happened in someone else’s life.
The reason it feels weird is because it was YOUR experience, and only YOU can feel what you felt in that lesson; and really, probably the only reason you feel nervous or awkward about it now is because you felt nervous and awkward about Skyping with your guitar hero and you just feel that feeling anytime you think about the lesson(It’s call the “spillover effect”). We weren’t there so we don’t have any feelings about it. Plus if you did something weird, just own it and be like “Hell yeah! That’s just what I do!” and many times people will respect you for it, as long as it wasn’t too offensive and you didn’t act TOO out of line.
I pissed myself once in grade school and thought everyone would remember and laugh at me for the rest of my life. You think I’m still walking around worried about people knowing that? Not even a little bit.
