My opening line to my students, and a recurring theme in my classes, was that the big design problem isn't designing a house for your parents or yourself, a museum, or a toaster, or a book, or whatever. The big design problem is designing your life. It's by the design of your life that you create the backboard off which you bounce all your thoughts and ideas and creativity. You have to decide what it is that you want to do each day.
Different personalities inspire me as an actor. Especially quirky personalities, maybe people I wouldn't normally get along with or be friends with - I find them inspiring for my work. I find sad emotions to be inspiring and stories of great people that kind of overcame odds.
