“I find the audiences very excited. But then they come and say to me, "Your optimism has brushed off on me. I didn't know we had an option. I feel so much better." They say, "Your optimism." And I am not optimistic or pessimistic. I feel that optimism and pessimism are very unbalanced. I am a very hard engineer. I am a mechanic. I am a sailor. I am an air pilot. I don't tell people I can get you across the ocean with my ship unless I know what I'm talking about.”
