I'd like to hear your suggestion. What kind of job is close to being a trader? If there is no choice, I'd ask if McDonald's can take me, just like what Kevin did in American Beauty.
I would only quite if I was prohibited from trading; if you can still trade, I think a good trader can adapt if he looks hard enough.
When looking at your question, I would suggest that you could rephrase it to say: If you had to quite trading, do you have an alterative way or plan to make money? For me the answer is yes, and I am currently doing that. As far as investing is concerned, it is only reasonable to think that you should constantly be looking for alternative ways to invest a portion of your trading profits outside of the market as a means of diversification.
Hey the majority of those who leaves trading are not choosing to do so they are simply kicked off from trading when they can't pay their bills anymore...
