1) pay off any high interest debt (i.e. credit cards)
2) save 3-6 months of the minimum living expenses you'd need for emergency
3) build a base investment in something like an S&P 500 index fund (minimum investment = $3,000) and then start learning more about the stock market or real estate by reading reading reading until you find out what investments best suit your personality.
I like Fool.com to learn about the stock market. They use methods proven over the year by Graham, Buffett, Lynch, etc.
