2. They Do What They Love

The late Steve Jobs said. "The only way to do great work is to love what you do."

It's perhaps one of the most easily identifiable attributes of those who earn a lot. Whatever they do, it's almost always easy to see that they love and are passionate about what they're doing. That's not to say that you can't or shouldn't do other work that helps lead to or sustain something you're passionate about. But if you don't ultimately pursue work in something that you love, the climb to wealth is always going to be uphill.
