Be careful where you invest, real stock investments is for people that have the expendable cash to take chances, it is a lot like gambling whereas with a mutual fund if you pick one that has been around a while you can see how it has done over the ling term. Just remember investments take time to pay off, there is no get rich quick scheme that works.
Most of all take your time and learn everything you can before investing, don't rush into anything and if an investment adviser is trying to get you to hurry and invest, run the other way.
