It doesn't help to continually try to convince them. You must first give them the basic information about SFI, and then, show how serious you are about your SFI business through time and actions you take. One of the greatest things I was able to show my husband besides, my income from SFI growing, was the product I won from a PriceBender auction and how little I paid for it. That really peaked his interest and he has told numerous people about it.
