Madonna wishes she could be President of the United States.

The pop superstar believes she would do a great job if she was able to take control of the country and her main goal would be to stop the country wasting money on "weapons of mass destruction."

"You can't really change much in one day. I think I would like to be president for a longer time. I wouldn't spend as much money for weapons of mass destruction but instead for education and art," she said when asked what she would do if she was President of the United States for one day.

Although she has achieved worldwide success, Madonna's ambition and drive has not diminished over the years. The 53-year-old singer attributes her success to her thirst for reinvention and never taking anything for granted: "It's harder to stay famous than become famous. I don't think there's a rule for that (staying successful). You have to really love what you're doing. You have to feed your soul with ideas and you're not allowed to stop growing as a human. That's what helps to create art. When it comes to my work I don't take anything for granted."
