I think investing in stocks and commodities is a great idea. this is because you are basically taking part in the growth of an industry, which means that if you invest in oil companies, for example, the more fuel is consumed—and the more oil is produced—the more money you can make on your investment.
It's also a good idea because it's not as risky as some other investments. You won't lose money if you buy stock in an internet company that goes under or if you buy land in a developing country without doing your research first. On the other hand, there's always risk involved when you invest in something new or untested—but that risk can be minimized if you do your research and invest wisely.
