If I could turn invisible for a day like Faustus does, I would like to use this power in order to gain more money.
This would happen in the following way. I would go to a bank and take money without anyone seeing me and the next day I would be rich. As I will have taken the money from the bank, like it were legal, no one would notice my fraud. I would choose to pursue more money and not power or fame, because I believe that for a rich person it is easier to pursue power or fame.
