i don't know i think the is to many teachers, when in actual fact the truth of the matter comes down to resources how to apply yourself and contacts, you could claim to teach people and claim thats the best way, but you could read a book and it can be totally worthless to what you posses. honestly people go around claiming teaching is the way, but they are just selling something and they don't even know half the time, if these things even work, they just know they are getting money for selling the book of "teaching" questionable.
