Many network marketers never follow up on their old MLM prospects, or if they do, they go about it all wrong.There are two sides to the proverbial coin, so you may want to keep the following in mind: 1. Your old MLM prospects turned you down (regardless of how long ago it was) for a reason. It may be that they didn't understand or accept the concept, or it may be that they had unrealistic expectations, or maybe they simply weren't willing to commit their money and effort.
