Brian Acton: "Facebook turned me down. It was a great opportunity to connect with some fantastic people. Looking forward to life's next adventure."

Few years later. Brian co-founded a company, without a salary for his efforts. Not long after, they sold their company to Facebook for $19 billion. The name of the company: WhatsApp.

Moral of the story: Don't quit trying. And don't worry if you get rejected. If something doesn't work out - just know there's something better out there waiting for you.
