You need some insecurity if you're an actor. It keeps the pot boiling. I haven't yet started to think about retiring. I was shocked when I heard about Paul Newman retiring at age 82. Most actors just fade away like old soldiers.
Friends are very important to me and I have always had many of them. There are probably many reasons why this is so but two seem to me more valid than any of the others I am a naturally friendly person and I hate to be alone.
