Mark Zuckerberg

Everyone knows Mark Zuckerberg started Facebook when he was 19, but because of that extraordinary beginning, everyone tends to underrate the role he has gone on to play, says Silicon Valley eminence Peter Thiel, who himself has had an outsize role in the tech revolution. Keeping the company relentlessly focused on the long term future, he is the opposite of a quarter to quarter Wall Street CEO, and thats why he deserves to be recognized as a great leader. We couldnt have said it better ourselves.
