I fantasize that our politicians have been moved by the dialogues of Plato, and thus contemplate the ancient conflict of the sophists versus the lovers of truth.

I don't remember much about the specifics of the economics courses that I majored in - I apparently internalized the key concepts - but I still remember vividly the thrill of reading 'Don Quixote,' Epictetus, 'The Aeneid,' 'King Lear' and 'Candide,' and how contemporary the stories and ideas in these old and ancient texts struck me.

I love reading Warren Buffett's letters, and I love contrasting his words with his actions. He's a very wise guy.

I didn't go to a business school. I didn't really study it.

Challenging the integrity of the non-proliferation regime is a matter which can affect international peace and security.

I get that I can come across as a show-off, but that is part of who I am.

I get mad. I get sad. I have all those emotions. But I just like to keep them to myself. I don't think my fans need to be bothered with if I'm mad or sad about something. I should just be concerned that they are keeping up with my music or I'm making them happy with my show.

I don't ever apologize for who I am because then I let someone else decide who I am.
