I am not currently, and never have been in Amway. I have been in two other MLM companies and achieved success in both. I believe that Amway is a legitimate opportunity, and may be a good choice for some people. Allow me to share a couple items that may help you examine it:
1) A common recruiting tactic MLMers use is to show you other people that are successful and telling you that you can achieve the same success. Maybe you can, but probably not. The truth is that each of us have unique gifts and resources - just because someone else did it doesn't mean that you or I can. Also, in MLM you rarely get the whole story - there are often other factors that contributed to those people's success - contacts they had from previous businesses, strong sales skills, or chance. (Some people achieve success in MLM by what is mostly chance - they recruit a few people who by chance turn out to be power recruiters.)
