Sounds like you're firmly on the road to wealth! A few things that can keep you from getting there:

-You stay in school til you're 30 getting a PhD in English and end up working in a bookstore (get a practical skill and get in the workforce ASAP!)

-Once you're making money, you spend more than you earn (Live a simple life and be extra frugal while in your 20s!)

-You MISinvest via options, market timing, high fee/commission investments, the wrong asset class (eg keeping all your wealth in cash) or other losers games. A Vanguard index fund or a Scottrade account is all you need.

Good luck avoiding these pitfalls. I started following the advice above when I was 22. I'm 30 now, have a substantial net worth and no money worries! It was worth the sacrifice.
