Hey Look, I'm being responsible with my Money!

Unless you really know what you are doing, I would advise that you invest in a mutual fund rather than individual stocks. Mutual funds are designed for people who want to invest, but don't have the time and/or knowledge to micromange their own portfolios. Of course, if you really pay attention to financial news and are confident that you know what you are doing, go right ahead with individual stocks.

Also, if you are looking at long-term investment, I HIGHLY encourage you to stay away from "risky" stocks. Long-term investment is generally best for slow-growth, low risk stocks/funds. Money market funds are also a good option. There is no need to take risks if you've got 30 years before you'll need the money.
