Re: Who has had success after a quick number close?
I think what he means is that by doing a quick number close, you are limiting yourself in your development. The most prominent one I can think of is that you don't gain the experience of having a longer interaction. Generally, your social skills are improved upon by socializing. If you limit the amount of time you are doing that, then you are limiting your own development.
