I would love to have a varied career, like Hugh Jackman. He started in musical theater, then established himself in film, but he still does a lot of stage work. And he does it all beautifully.
One blob of red in the wrong place and the audience isn't looking at the hero, they're looking at a patch of curtain (or something similar) and your whole effect is lost.
I had a ninth grade teacher who told me I was much smarter and much better than I was allowing myself to be.
