When I started out, I wrote the songs, recorded the songs, mastered, mixed, did the artwork, made the packaging and did the distribution, all myself. Now I understand what everyone's jobs are, who is doing them right, and who isn't.

Hip-hop educated me about other forms of music, because it sampled from all different styles.

Industry executives sacrificed art for what sells and mega-stars now saturate the market with the same tired lyrics.

In school, I studied psychology, linguistics, neuroscience. I understand that there is a real lack of respect for the brain.

My trademark at CNN was really asking insightful questions and making sure people are understanding the connections in humanity, and I think that is the core of education.

One of the issues I kept saying to my students is you have to learn to interrupt. When you raise your hand at a meeting, by the time they get to you, the point is not germane. So the bottom line is active listening. If you are going to interrupt, you look for opportunities. You have to know what you're talking about.

A lot of people criticize the primaries, but I think they are absolutely essential to the education of the President of the United States.

I went to the London School of Economics to study sociology and psychology on a serviceman's grant.
