• Absolutely zero fear of risk; he is willing to put his entire bankroll on a single project (500m+ invested in his own companies)
• Arguably the most brilliantly diverse engineer of our time.
• His level of optimism and determination is unmatched by anyone of our era. Elon will literally not stop a project until it succeeds, regardless of its size (http://www.wired.com/science/spa...)

Forget about iPhones and iPads, Elon is trying to solve some of the biggest problems of this world's future.

And he's doing so without being properly noticed. So my perspective; that alone makes him the greatest Entrepreneur of our time.
