If somebody tells you that forex is a way of making a living, just laugh at him.
Forex is a high risk investment. The idea is that you use spare risk capital and withdraw profits regularly.
The only way to make a living from investing is to have a varied portfolio, of which things like forex, stocks and commodities can be placed in the high risk section but are by no means your only form of income.
Forex trading for me is just a way of buying extra things. For instance over the last couple of months I've paid for new laptops, business class plane tickets to a few places and a rather expensive day at Toys R Us for the kids

They also now have one year unlimited passes to go to Disney World any time they like. Little things that I probably wouldn't have bought without those forex winnings.
I did try to live off forex for about 6 months a few years ago. I was compounding and taking out living expenses and having a great time. However a couple of bad decisions pushed me back to 1/2 my initial capital which made my earnings potential very much lower so I had to diversify my way of earning and my investments.
So by all means, trade carefully and consistently, withdraw often and buy yourself some toys/holidays etc... but dont think forex is your ticket to the easy life.
