PayPal cofounder and billionaire investor Peter Thiel has long been known for his contrarian views. He’s paying entrepreneurial kids to drop out of college, and is building a floating, autonomous island. He doesn’t like to hire MBA grads, and hates CEOs in a suit. It’s why the first question he asks any job candidate or startup pitch is: “What important truth do very few people agree with you on?” Perhaps, that kind of thinking is what’s made him one of the most successful entrepreneurs and investors of all time.
