First of all, you should remind this affiliate why he join SFI.
Make him say in his own words what he expect from this business.
Then you should show him some testimonials, success stories and focus on how long people took to get where they are now in their success.
Tell your affiliate to take 1 action at a time and conitnue climbing his own ladder to success. There is no limit of time and no limit of earnings.
Your support and help in finding his way will make you both happy and successful as a team. And that is a very good story to tell all your future affiliates.
