Nouriel Roubini

I believe investors should invest for the long run, so I don't buy and sell. I usually maintain the classic index of global equities, diversified U.S. and global and emerging markets, and when the risk is larger, I diminish the amount in global equities and put more into liquid assets - but very irregularly.

I was completely with the reality TV boom for a while. I really liked a lot of the reality TV, and the one that lost me was the ballroom dancing one they do, 'Dancing with the Stars.' That was the one where I watched it and I was perplexed. I thought it was really boring.

My venture investing career has three phases, all roughly 6-8 years long. The first, at Euclid, was software to Internet. The second, at Flatiron, was Internet to bubble. And the third, at USV, has been web 2 to mobile. I have always used a new firm to denote a new investment phase for me. Throw away the old. Start with the new.
