I'm in the telephone business to make an appointment with customers. Then interview interested customers, always feel that their speech skills are not good enough.

Salesman is a very broad profession, and successful people are different, especially in appearance. Different styles will attract different people's attention. The cultivation of style, in addition to recognizing one's own advantages, is very important to repair one's own weaknesses, in other words, to keep learning and accumulating. You can talk without Kan Kan, but you can definitely talk about the main points and win the favor of the other party in the shortest time with your rich business knowledge and experience. There is no need to argue, but you judge the situation, advance and retreat, conquer your opponent with data (mathematics) instead of language, and you will practice hard work instead of showing off your legs. The growth of business, in a sense, is the length of time. What you need now is a complete self-cls scheme.
