As long as your intention is pure, and you know what you're in it for, then you're alright. And I'm in it because I enjoy it. I take it seriously... real seriously. I mean I could sit and talk all day about the music.
I use something that is a real staple in the directing world. It's called a dance floor. You lay it down so that it's so smooth you can roll around, and you can put furniture on top of it. It's seamless and you don't see it.
