I think in most jobs, you get better as you get older. You gain experience, you gain knowledge.

There's no question that as science, knowledge and technology advance, that we will attempt to do more significant things. And there's no question that we will always have to temper those things with ethics.

You don't have to be a brain surgeon to be a valuable person. You become valuable because of the knowledge that you have. And that doesn't mean you won't fail sometimes. The important thing is to keep trying.

If you go and talk to most people, they mean well but they don't have much of a breadth on education, of knowledge of understanding what the real issues are and therefore they listen to pundits on television who tell them what they are supposed to think and they keep repeating that until pretty soon they say, 'Oh, well that must be true.'

I wish I had known more firsthand about the concerns and problems of American businesspeople while I was a U.S. senator and later a presidential nominee. That knowledge would have made me a better legislator and a more worthy aspirant to the White House.
