Really Great Entrepreneurs Have…

According to Astro Teller:

Really great entrepreneurs have this very special mix of unstoppable optimism and scathing paranoia. If you don’t have a tonne of optimism, you’re not going to make it… you won’t be able to evangelize to everyone else. On the other hand, if you aren’t constantly paranoid about what can go wrong and put plans in place, then you’re going to get bitten at some point.
