It has changed my way of thinking in many ways. For me it was worth every penny. Van does not give you a black box, or advice what you must use to become a success overnight. If you are looking for that, then you will be disappointed...
If you are looking for somebody to help you organize your thoughts, feelings and you want to learn how to think to accomplish something(like beeing a trader), you will be very excited about these courses.
I do not know if his son still trades or not. But what has this to do with Van's work?
There are so many criteria that comes in to play to be a successful trader, that not everything can be solved by a coach or a mentor.
If you want to be a great basketball player, you need some other things also, then only coaching from the coach of Michael Jordan.
