Not sure any of the People that signed up for SFI are lazy they did make the effort. The motivation part is up to the Sponsor, some do it by telling them how much money they have made, some by telling them about a product they use and how much they like it and how easy it is to sell to others.
Boils down to do as I do not as I say. Show them how do not tell them how. You motive by doing.
