I’d heard Facebook was founded by some Harvard dropouts, but I didn’t know much about start-ups until I took a class my senior year about Silicon Valley entrepreneurship. And then I understood: Oh, this was the land of hungry, foolish dreamers who were given the chance to build their version of the future with a little help from venture capitalist fairy godparents. This was the land of innovations borne from a mix of smart minds, iron resolve, lucky timing, and a whole lot of duct tape.
