"You're going to hear all the reasons for saying no." ~@davidsze
Forbes has a video in which David Sze talks about how to invest when others think you’re crazy:
Almost every investment you do that turns out to be really interesting — at the time a whole bunch of people are going to think you’re crazy.
You’re going to hear all the reasons (for saying) no. And how do you decide which ones are the reasons to say yes...
You have to look deeper, look “one level down” below the obvious, to see what others aren’t seeing, he says. Despite the naysayers, Sze was convinced by Zuckerberg as a person, as well as the extremely high levels of engagement and passionate users of the site.
