Elon Musk is all about solving problems, but he couldn't reach his level of success without some help, and so when he looks for people to help him expand his company, he looks for people with the same mentality. And how does he find these people?

Musk revealed in 2017 that when he's building his team he asks them one question: "Tell me about some of the most difficult problems you worked on and how you solved them." He explained that "the people who really solved the problem know exactly how they solved it. They know and can describe the little details.”

Despite him being the second richest man in the world, for Musk, it was never about money. The combination of his future-thinking and his focus on solving problems is what makes him successful and provides him with a hefty paycheck.
