The best way is to learn by your self. It is not hard. If you have a high school diplomer, you should be able to do so.
WFG is a good place to learn, it is cheap. You spend $100 to get many training.
But there are many sales try to sale you somothing and earn your money. before you understand, never buy anything. they do not force you buy. Like you and me use this web site for free, we need to watch those ads.
Let me know if you need to know how to join.
