I see
MLMs as vile because it's true that the only people who
really get rich off them are the people who start them. I've met many people who were sold on getting rich because they bought into pyramid schemes like MLMs. Anless you have something that can really
help people, I would hope you don't spend your time creating something as shady as mlm. If you really want to get started doing that stuff, the best way would be to imitate the people who do it best (study their marketing/business strategy and work from there). Maybe the
Wikipedia article will help you?
Another thing to keep in mind: are you wanting to do this because of passion or greed? Passion = success. Greed = failure.
