You could have all the money in the world, but you have to be smart enough knowing how to spend it. I really try to be on that smart money side. Once you make a serious mistake you can suffer five or six years, and I do my best to avoid serious mistakes.

I work 12 to 14 hours a day, and in the spare time I do sport.

Money is not the thing that drives me. I like to develop assets to create value. No one cares how rich you are or what your ranking is in Forbes magazine.

I am addicted to sport. Without sport, I feel bad.

Some people say the reason I am not married is that I don't understand small business and the toughest small business in the world is a family. But when you are happy and feel every minute of your life, what is the reason to get married?

Even before my parents died, I felt all the responsibility to my family. I don't know why. In any business, any relationship, if something goes wrong, I feel I am to blame. It's something inside me.

I never count my money. I think that's your job.
