My view is that at a younger age your optimism is more and you have more imagination etc. You have less bias.

I approach every problem with optimism.

Life is a beautiful, magnificent thing, even to a jellyfish.

We must laugh in the face of our helplessness against the forces of nature - or go insane.

It's a beautiful day, the sun is shining, I feel good, no one is going to stop me now.

There is something in the human spirit that will survive and prevail, there is a tiny and brilliant light burning in the heart of man that will not go out no matter how dark the world becomes.
