Options Trading Tutorial

Am I better to start a business or invest in the stock and forex markets? (please help/advise)? I am 18 years old and since I was 13, I've been looking for ways to get rich and become a multimillionaire. I have been thinking about my various options with my few thousand pounds I have tied up in the bank, and what I've discovered is that I feel most passionate about internet and appication businesses, i.e. facebook or iPhone from what I've heard about their potential, but still feel I'm leaving something behind withous stocks and forex. I want to know in your opinion; Would I be better to invest in Forex and stocks as a business to become a multimillionaire quickly, or would my best chances be in starting a business using the iPhone and facebook application platforms to become a multimillionaire quickly?
