There's a lot of craft that goes into achieving a hit song - at the beginning of your career, you're usually more inspiration than craft, and you get great when those intersect. A skilled songwriter can get you to that intersection.

I don't think people really understood what I did. And you know, in my book, 'A Helluva High Note' deals with my back story, that I was a songwriter, that I spent years trying to hone my craft and being rejected and then finally becoming a successful songwriter, record executive and publisher.

A lot of people give actors credit when they gain weight for a role in a drama when they win an Oscar, but when you're doing a sitcom, people don't give you a lot of credit, because you've got to keep your weight on for five or six years if it's successful.
