There are indeed many private education courses for Wuhuan people, and I have taken several courses. In a short period of time, you can really close some customers under consideration, and some routines and closing psychology are also useful, but to be honest, the growth of performance mainly depends on whether you have any specialties that are worth paying customers. For example, if you are the only one in the whole gym who will recover after childbirth or have the best reputation, customers will naturally come to continue their classes. If your own ability is not enough, no matter how many routines are only one-time transactions, it is your professional skills that really make your performance last long and make you valuable.
