i just remembered a cool story.
when i went to college doing music biz promo one of my teacher drummed in a semi famous band from the 60s and 70s.
he told us about this gig they did in london when they were starting out. they were backstage and this prat from the other band was posing in front of a mirror and pulling moves, telling himself "you're the man, you can do this" etc...
being a bunch of weegie scumbags they just laughed at the guy.
they went out front to check the band out and the guy was amazing. all the moves he'd been practicing looked so cool and natural. after a few songs he stepped up to the mic and said: good evening i'm mick jaggah and this my band
