50 Cent doesn't think his $400 million fortune is enough.
The 'Candy Shop' rocker says his troubled upbringing made him believe that having a lot of money would solve all his problems, and even though he no longer thinks that is the case, he always strives to do better.
He said: "$400 million? I'm not sure how much I have, but that sounds great. I don't really think it'll ever be enough. I used to equate success with my finances because I didn't have anything, and when you don't have any money, it seems money is the answer to all your problems. Then you get money, and you realize that you've got a whole new set of problems."
Despite his worldwide successes, 50 - whose real name is Curtis Jackson - insists he is still down to earth because he is happy to travel economy.
He added to Interview magazine: "I really don't mind flying coach if I have to. If the front of the plane is sold out, I'll sit in the back. Some people are like, 'Oh, first class is sold out. I can't go.' I guess they care about people seeing that they're not sitting in first class. "But I'm clear with my financial space - I don't need to get any validation by someone else who sits next to me in first class. If you think a seat in first class makes you a star, then you're not one."
