I just don't eat too much. That's never been my problem.
I was initially a leading man, but only on television.
Being able to fantasize for a couple of days at being a rock singer surpassed most things I've done on stage.
Improv is not something I had a lot of experience with, because for a long time, my only experience in front of a camera was all television, which is pretty rigid script-wise, except for the occasional scene where you toss in an ad-lib just to elongate something.
Then, at some point, you get identified with certain things.
You always know when something works it's a result of everything firing on all cylinders.
