I think there's such a thing as a performance gene. If it's in your DNA it needs to come out. For me, it originally came out through music, then segued into acting and came out through there. I always needed to get up and perform.
That's what acting is about, Funny wigs and voices, that's what we do.
Then, at age 20, I discovered theater sort of by accident. Quite quickly, theater became more important to me than music. I began to realize that maybe my talents as a musician were quite limited, or had a ceiling to them, whereas acting seemed to sort of stretch before me. I got very passionate about it very quickly.
