I am bearish on the long term prospects of the economy and the stock market. Despite my feelings about the long term, I went net long a few days ago and have caught a very nice trade. A few years ago I would not have been able to do that. The possibility that I would be correct in my long term view and lose money at the same time would have been more than I could handle.
It took me nine years of trading until I was able to trade against my long term view. Since then my results have improved dramatically. I am not sure if this has been the only factor but I am confident it has been one of them.
