Dustin moskovitz -- It's harder than it looks

Dustin Moskovitz co-founded Facebook with Mark Zuckerberg and it made him a billionaire. Now he's working on another company, Asana.

Moskovitz created a startup deck that's full of advice about how to launch a successful company and explains what it takes to be an entrepreneur. It's not as glamorous as Hollywood and the media make it look.

It's important to know [why you want to start a company]," Moskovitz explained to a Stanford class. "You may have been mislead by the way that Hollywood or the press likes to romanticize entrepreneurship."

"You can't not do it in two ways. One is you're so passionate about it that you have to do it and you're going to do it anyways. This is really important because you'll need that passion to get through all of those hard parts of being an entrepreneur...The other way to interpret this is the world needs you to do it."
