Here's a tip from Kim Klaver - say no before the prospect does! I recommend her How to Build a Giant Hap CD for loads of tips. Basically you say "OK, no, it's probably not for you, sorry I mentioned it" and move on to the next person. Just don't waste your time on people who aren't interested. You know what will make them interested later? You making a lot of money in GDI. It's amazing how many people will listen when you've made a million (since you're going to think anyway think big etc )
To answer the earlier question here in the UK we pay taxes on earnings from network marketing and pyramid schemes are illegal (as I expect they are in the US). I once got into a stupid and futile debate in which I explained this and explained that if I was doing something illegal I would be stopped. I then asked "is your Avon rep a criminal? Are they about to arrest the Mary Kay lady?". One of the responses went something like "yes, I've heard that argument before about pyramid schemes being illegal but I still think it's a pyramid scheme. Well duh ...where do you go from there?! This was just before Christmas when I really didn't have a lot of time fo messing about on forums. I was very depressed that my chosen career was being trashed. I did however get several e-mails from others who had been following the debate and were impressed so all was not lost.
