Too bad I won't ever be able to test this statement because my stage-fright would stop my heart before the band even played a single note... Anyway, nice read.
The first show I ever played was spent looking down at the ground while playing guitar and singing as my hands and legs shook. I'm sure the next few shows weren't that much different. Now I think I'm most comfortable on stage, mainly because I'm doing what I love. I'd say if you're interested in making music and such, just go for it. Stage fright disappears, trust me.
