There is definitely a fine line between nagging and persistence. Who wasn’t told to stop “nagging” when they were a child?
The truth is that children are the very best salespeople. They take the art of persistence, and oftentimes nagging, to impressive levels. For salespeople, it is instrumental to understand where the line is drawn between persistence and nagging. This requires the ability to recognize when a request or a question is self-serving and doesn’t offer a benefit for the person being queried.
