'Quantum Leap' gave me a huge opportunity as an actor. The nature of the role and it's demands allowed people to perceive me as a versatile actor, and the wide success of the show around the planet gave me a certain notoriety that helped me get other work.

The reality of our business is that for every actor who's rolled up his tent and given up and gone home, the next day you hear about some shoe salesman at Macy's who had this audition and now he's Harrison Ford. There's always that carrot out there in our business.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
