Start trading. If you start at a prop firm then be sure to talk to as many people as you can. You will be suprised at what you learn. If after a couple of months things aren't working out then take the Intle job. I had a similar experience where I took a job trading not knowning anything about trading at all. Needless to say I was done after 3-months then I took an engineering job. Despite my unsuccessfult first attempt at trading I would not trade the experience for anything. Until that point I didn;t even know what trading was. My investment and finacial IQ was practically zero. I learned motre in those 3-months about about money that I had learned in my previous 23 years.
The biggest difference is that within a year after graduating I got married and my wife has two kids from a previous marriage and we bought a house. So for right now trading for a living is out of the question for me. I do trade on the side as well as attend school for a masters.
Don't underestimate either route. Trading is extrememly tough under any circumstances, especially when your lively hood is on the line. Although I can say that working a regular job, working on a masters, trading FX and raising a family is one hell of a task as well, but I do not derive my living from trading. Yet!
With that being said, now that I have started trading again I would do it full time if I could. There truly is nothing like it.
