True, my lack of money does not have a positive influence on my trading, but since my immediate survival does not depend on the outcome of any particular trade, these issues take a back seat to more fundamental ones: When I doubt myself and my ability to be a profitable trader, that is when the losing really starts. But as I keep making more and more and losing less and less, I also gain more confidence. Not in any particular trade, but in my ability to make money trading and to increase the rate at which I make money. There is also another thing that is very important to me and my state of mind for trading: I happen to be good with some instruments and strategies and suck at others. The way I deal with this is to keep in mind that I do have one strategy that makes me money, and if worse comes to worst, I can just give up on everything else and keep making money quite consistently. Of course, that is also just an illusion, because market conditions change, and that is why I keep experimenting with different instruments and approaches.
Also, I should add one more thing: Because I worry so much about money, I have more of it than the average guy, meaning I have no debt whatsoever. It kind of helps not having a monthly minimum payment of $2000 to pay off that overpriced car and all the big screen television sets and all terrain vehicles you just HAD to have before you could afford them...
