I have same problem with you, but I still work with him. I tell him the important of duplication in this business, I tell him how to do that. Till now he still not interest about recruit affiliates or otherwise engaged in duplication, but I will never give up to him.
I believe one day he will know the important of duplication, and will work hard for that.
LEAD BY EXAMPLE
I do this and I hope you can do it too.
