Big Sean

I grew up on the west side of Detroit - 6 mile and Wyoming - so I was really in the 'hood. And I would go to school at Detroit Waldorf, and that was not the 'hood. Growing up in Detroit was good. I had a good perspective, a well-rounded one, and not being one-sided.

This rise of the new global mega-rich is happening as established institutions are falling. The fall runs the gamut from the music business and traditional media to the Detroit automakers who find themselves obsolete, outmaneuvered, and out-priced by entrepreneurs in Silicon Valley, Mumbai, Shanghai, and even Siberia.

I'm a huge, huge fan of photography. I have a small photography collection. As soon as I started to make some money, I bought my very first photograph: an Henri Cartier-Bresson. Then I bought a Robert Frank.

At one point, I didn't get out of bed for, I think, three months, and I went down to the bottom of the hill one day and I had to call somebody to get me to come back up - come pick me up because I couldn't physically walk up the hill.
