What Makes a Good CEO?

Tech CEOs are grabbing their fair share of headlines, per usual. 

Mark Zuckerberg is in the news again in the wake of a negative new book about Facebook and a controversy over his Fourth of July watersports moment (patriotic or not?). Jeff Bezos and Richard Branson are duking it out over their journey to space, or somewhere close to it, igniting (in my opinion) far too much discussion about their extraterrestrial extracurriculars.
