Bob,
I'm sorry to hear about your frustrations. My wife is also a Stampin' Up! demonstrator in Stewartstown, PA. While she has also worked very hard for a couple years (and we've moved several times), she's kept a persistent, positive attitude and it's paid off. While I can't say that she's made her millions from Stampin Up, she has created a reasonable flow of income, but, more importantly, she's developed friendships across the country through her SU blog www.stampthat.com, and she really enjoys what she does.
While any kind of networking business can become a frustration, it's the same way with any kind of start up. It does require significant investment of time, energy & money to make a business really take off and succeed.
