Entrepreneurship Lessons from Jack Dorsey

It's one thing to have a 'hit' company, and another thing altogether to have two such 'hit' companies. We already know that Twitter is among The Big 5 in social media. Square is apparently big, too, and I imagine getting bigger.

But what makes for a successful entrepreneur? Maybe it's Jack Dorsey's zen-like personality yet ponderous demeanor. Maybe his belief that everyone in the organization has a right to know what's going on.
