Quote from Joab:
It's actually a very different reason then most people think.
The market cycles over an average 7 year period.
The reason that traders fail is because of the constant CHANGES that the market cycles through.
In my opinion you can not call yourself a professional trader till you have last through 7-10 years and remained consistent.
After 25 years in this biz I'm still learning every day.
Well said.
Its something you have to live through..... not read about in a book.
