Reminds me of when I was doing the Amway thing. People would ask similar questions, although most had to do with MLM being "illegal". Of course it was legal and even though I reached a very successful level, one of the people I sponsored soared right by me. My point is that anyone, who puts in enough effort and invites enough people, can do as well or better than their sponsor. A better question would be, "am I a good teacher?"
