"The attributes for entrepreneurs cut both ways. You need the ability to ignore inconvenient facts and see the world as it should be and not as it is.

"I can't say I'm not grateful to have journalists writing about me as a genius. But I know it's not true. I'm not confused. I understand that success comes through a lot of failure and a lot of very embarrassing failure. People want to create the next Facebook, but they are too afraid to create the next Facemash."
