Replying to Who here has started to invest some of their money?

So I don't have a whole lot in savings, however I do have a few grand that I would love to see grow till I'm ready to buy a house/nice car. Basically what I'm saying is, I've got a few grand that I'm willing to invest and not be able to touch for 10 years or so. Basically, where should I start? Anyone else here in their early 20's that have started to invest some of their money? When I say "see my money grow", I know that 3 grand won't turn into a million. But cash sitting in savings for ten years will gain chump change which is why I'm looking to invest and earn some real interest. So for my fellow NSer's who have started invested at a young age, what was you approach? Like I said, not expecting to get rich, just better off than if I had let my money sit in Chase savings and gain .01% interest.
