I for one will never depend on the forex market to survive! That is just ridiculous! When push comes to shove I don't want the mind set, I have to get my 100 pips this week or I am going to be evicted, what could be worst for your trading!
You do not have to be a full time trader to be profitable! I think the real advantage of going full time is the learning experience. It will probably cut down on the learning curve a lot, but to depend on making pips so your not homeless would totally destroy progression in forex!
Don't get me wrong! I am not saying it is not possible to making a living off of forex. By golly I plan on making my first million in forex between the ages of before 25. I am nearly 19 by the way. So what would it take for me to make my first million dollars in forex in less than 6 years? It takes 2,000 USD, 130 weeks, and 5% weekly returns! You know what, I can pull that off! No doubt, but first how am I going to survive for the next 6 years? Well I am going to get into the automotive industry. Every morning I can wake up go fix 8-10 cars a day and go home and realize, everything I have is here to stay and only better things are to come once I hone my trading skills!
We take a gamble in life. We assume we will have our carriers and that we are relatively safe. But that really isn't the case. Company can go under, could get laid off, all these are realities we have to face. But to face the reality that you need to make so many pips a week so you can keep a belly full and stay out of the rain would be way more stressful.
So unless you can afford to sit home and trade and not have to worry about paying bills from your capital gains from forex I would not suggest going full time at it. However, if you are lucky enough (or unlucky) to be in a situation to trade full time then I say go for it!
All I know is that I am going to live as cheaply as possible and roll in some green backs with forex. I believe my ambition will drive me further and I won't be stop and I will make my first million before my 25th birthday with Forex. What a wonderful next 6 years this will be and for many more enjoyable years after that

Because you know after your first million you can't stop
My final note, you can make a living trading forex, but you shouldn't
