Stay in school to give yourself a head start, THEN start your own business. Don't spend your life working for corporations, paying into pensions and stock options. It's the fastest way to achieve mediocrity. Almost nobody becomes a millionaire through their job alone (except for the very few that achieve senior status, but they will have to sell their souls to do so).
The best advice is to eliminate or avoid debt, invest in a portfolio of high return opportunities, use your education and job to learn to do something for yourself such as business / investments, continually educate yourself, get an alternative education to supplement your academic education, and don't get into debt (oh did I already say that? I'll say it again "DON'T GET INTO DEBT") ;-)
