Well, that would be because many people won't listen if they think it's Amway, cause they have their mind made up already. But if it is presented to them differently, they keep an open mind. Amway has great products. We were in for about 5 years, we made zero money, but we did learn a lot of other valuable things that have helped us in our personal lives, and our other business ventures.
Please consider the business section of your local bookstore, the library, or maybe a local business owner/mentor next time you need some learnin' on business. You'd save a lot of time and money compared to the Amway MBA you earned over 5 years.
And if you consider the time well spent, I'd say you still didn't learn enough. Good luck, regardless.
