As much as I have seen this asked on here it dumbfounds me. It always ends in this arguement that pretty much says that most people do not need it. It's for people who need the skills to compete and succeed in business that are clueless blind men and women. Nothing that any of these groups has is no real secret but I bet to some they offer real value. I just can't see paying money to have someone show me a way. I would rather learn it my way and then drive on that way.
