You've got to validate every day. There are those who just put a stamp on it and say, "This is gonna be a good day and I'm not gonna let anything else make it a bad day."

I'm retiring the Mos Def name after 2011. I'm actually doing it.

You have to be an extremist to believe that you're gonna be the president of the United States and your name is Barack Hussein Obama! And he's using extreme methods, but his application is very smooth. Michelle Obama is extreme, her presence is extreme. And it's an extreme good. Extreme is not negative.

I'm not shy about heated debate or passionate discourse, but when people get crazy or rude, that's a buzz kill. There's got to be a better code of conduct, some basic etiquette.

To me, it's like happiness is about happiness, but happiness is a fight.

If you're going to do Chuck Berry, you got to, you know, go all out, and the duck walk is just kind of you know, cursory. That's like standing.

I like to read the 'Financial Times' when I'm traveling. 'Economist.' 'Ad Busters.'
