I believe that the best way to show your affiliates the importance and success of duplication, is by you yourself. YOUR success will make then want to say, "hey, if she can do it, so can I." Myself, if my upline is not following their own advice, I would be hard pressed to want to follow them. but seeing all the badges and work they done, makes me think that I'd like to do the same thing. Encourage them to ask questions.
