Well first and foremost I believe that a positive attitude is key to duplication. If you possess a positive attitude at all times you have a greater chance of creating a downline of positive people.
Also,be sure to point your new affiliates in the right direction. Tell them all they need to do to succeed in this business is to follow the "SFI BASICS".(No need to complicate SFI) If they do this they are sure to succeed and therefore so will you...duplication has begun!
