I was just pitched ACN by a good friend who seemed to be brainwashed. He is a great salesman, intelligent and thoughtful. Unfortunately, his pitch degraded into a berating of my job, ambitions, income and foresight. Not cool. Please do not get sucked into this and suffer a loss of friends.
My experience with MLM schemes are always the same. I listen carefully to the idea. I calmly explain (if possible) that the idea is not new. I then listen to the objection rebuttal. I do my research, looking for pros and cons. My decisions thus far have been to avoid paying or acting to involve myself at all.
Any MLM I have approached or have been approached by has been a losing proposition for anybody I know. Friends who have pressured me have gone away in embarrassment or apologized for their actions.
