Well, Forex can be compared to other businesses because if you wanna be successful you have to work hard and be as professional as possible, just like any other business.
No, Forex is not an easy to make huge money, only people who are trying to sell you useless trading systems say that. Don't ever believe those ads that say that you will make 5000% a year, because if you target 5000% you will almost certainly lose all your money after a few days due to the excessive leverage.
I'll just give you an important statistic: it is estimated that about 90-95% of retail traders (that's us little guys) lose money, and I bet that most of them thought this was easy. If you look at the trading contest, only about 20% of the traders end up the month with more than the initial $100.000. And if you look at the average end of month capital for all months, it is even much less than 20%... So breaking even is already very good!
Once you start trading with real money (not demo accounts) you will see how much more difficult it can be psychologically. Only time and experience will help you beat the psychological hurdles of live trading.
Now, having said all that, achieving profitability is surely possible and many people do it and make a very good living, just don't expect to become good at trading when you start. I can tell you my personal experience, I was completely useless in the beginning, lost a lot of money, kept improving, and about 2 years later I was a reasonable trader and was on my way to develop my current trading system. Now I trade full-time, and have been doing it for almost 3 years now, and at this point trading Forex does seem easy, even though when I started it was the most difficult thing I had ever done.
By the way, I don't know what you consider huge money, but I certainly do not make silly % a year (and I don't know ANY professional trader who does), you need to have realistic expectations and enough trading capital.
