Maybe the alter-ego thing would be a good idea for me... Although usually I just imagine what one of my instructors would do, and try to replicate what that would be as best as I can. I usually don't actually succeed in looking sexy at all (just watched some videos - ouch!) but at least you can tell I'm trying, which at my level (beginner!) seems to be good enough. And I figure, if I work long enough at pretending to be confident and sexy, eventually, with enough practice (as everyone else has been saying) it'll come true!
