Each one of us requires the spur of insecurity to force us to do our best.
I think we all have blocks between us and the best version of ourselves whether it's shyness insecurity anxiety whether it's a physical block and the story of a person overcoming that block to their best self. It's truly inspiring because I think all of us are engaged in that every day.
The quickest way to defuse fear or insecurity or anger is usually humor. I think comics figure that out quickly and once you figure it out you think 'Hey if I can do this and get paid that would be kind of cool.'
Anger is a manifestation of a deeper issue... and that for me is based on insecurity self-esteem and loneliness.
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.
