Sales don't have to be able to talk. According to your occupation, telling your customers what you know is actually something that will bring them health and benefit them. Ordinary customers will not resent it. As long as you have good professional knowledge, customers will trust you for a long time and help you promote it. Slowly, your customers will come. Remember not to worry, just because you didn't perform in the early stage doesn't mean you can't, but your time hasn't come yet.
