You can't assure duplication in your downline. Many will not become active. But the ones that do become active, you need to explain to them what you are doing, assure them you are there to help them, and continue to communicate with them. I have found that if you keep in contact with your downline, be it PSA or CSA, they are more inclined to continue logging in on a daily basis and doing what needs to be done. They see you doing it so they do it. Lead by example and follow the Rules of Success.
