Everyone of your downline can be a superstar. In my opinion, you don't have to identify them, they will identify themselves. I treat all my downline the same. Some may become superstars immediately while others may not shine for several months.
If I tried to identify "superstars" and treated them differently, I would miss some. So I suggest treating all downline the same, let the superstars shine on their own, and be available to answer questions to help all who need it.
