Ways to make lots of money

Play the stock market.
While the stock market is not always the safest bet, it can make you a lot of money. Be sure to do your research so that you will be less likely to lose your money. Don't invest what you can't afford to lose. If the stock does go the direction you want, you can make some serious cash.

401k plan.
While it does take a long amount of time to make money through a 401k, it is a great idea to start young. The longer you leave your money in a 401k the more interest you will draw and the more money you will make.

Start your own business.
If you have the money to start your own business, you should try it. This way you will get to be your own boss. Just make sure whatever you start that you will make a profit off of it. For example, don't try to open a store that sells coats in the Bahama's.

eBay.
Many people use ebay to make money. You can also set up your own store here. I've heard of people going to garage sells, pawn shops, etc and then selling it back on ebay for more than 10 times what they paid.
