My major contribution to the format was to suggest that I be able to step out of the plot and speak directly to the audience, and then be able to go right back into the action. That was an original idea of mine; I know it was because I originally stole it from Thornton Wilder's play Our Town.
Fall in love with what you're going to do for a living. To be able to get out of bed and do what you love to do for the rest of the day is beyond words. I'd rather be a failure in something I love than be successful in something I hate.
