I'm not as hopeful as I was when I was young.

Optimism is the key.

There's probably a little greater case for pessimism than optimism. But I do not rule out optimism.

If you were an optimistic teen, then you'll be an optimist at 80. People's reactions to bad events are highly stable over a half century or more.

Only the really young are fearless, have the optimism, the romanticism to take unimaginable risks.

When you are young you don't always realise how full of doubts everybody is.

I understand the concept of optimism. But I think with me what you get is a lack of cynicism.

What I've really learned over time is that optimism is a very, very important part of leadership.
