Really struck a cord with that post. That you are open about self and doubt speaks well for you. I think we have all experienced the same.
I see investing as similar to craming for a test. Some times there is just too much to learn in a short time. We can only learn at our rate because things need to be mulled over in our subconcious to fit into the directory, like that...It is good for me to step away from trading, its just too intense for me on a continuous basis. Hope this relates somehow. Again great post.
