You don’t have to control your thoughts; you just have to stop letting them control you.
No matter what you’re going through, as long as you have some specific emotion, whether it’s positive or negative, it is all stuff that you can use on stage.
When I’ve had hard times in my life, the one thing about being in TV is that it’s positive. I withdrew to ‘Cheers,’ it was familiar in that it was family. It had a kind of realistic positiveness to it.
