As I saw my 60th birthday approaching, I thought,What did 60 mean to me? I figured I'd probably live until I'm about 90, which meant that I was at the beginning of what I call my third act. As an actress, I know how important the third act is. It makes sense of the first and second acts. You can have first and second acts that are interesting, but you don't know what they mean. Then a good third act pulls it all together. And so I knew that, because I sat by my father's side over the long months when he was dying.
