Forex can be very profitable if done carefully. First step is to understand the Forex market. Before you begin trading learn the basics, this website is awesome. http://www.informedtrades.com/trades.php. It's absolutely free!
For beginners, risk only 2% of your total account value. This is very, very, important. Only about 23% of those who trade Forex are profitable according to my broker. Controlling one's greed is one of the biggest challenges in being a profitable trader. Trade, don't gamble. Trading is based on information and market trends. Gambling is based on feelings. Get comfortable with the fact that you're going to have a losing trade now and then so don't get discouraged. Good fortune to you!
