I did a quick Google search and found this question to be the top interview query. So if you’re applying for a job, better have a good answer. One site listed lots of answers, here are some favorites:

What made me think of the question was a recent Economist article about a brilliant Indian businessman named Rakesh Jhunjhunwala. He’s been called India’s Warren Buffet. The 52 year old made himself a billionaire by judicious trading since he was a teenager.

He understands that the riches and fame are transitory. He names his true motivation below.

“I’d be lying if I said I didn’t like the money, but that’s not what motivates me.” So what does make him tick? “The thrill of being proved right.”

As you work and negotiate with others, remember that this simple motivation strongly drives lots of successful people. Remember when dealing with your customers that they may care more about being proved right than about the money.
