The main thing is that you practice more, learn more, sum up more, and learn more lessons (consult colleagues and leaders more). You run more, make more strange visits, and find a small shop to practice your speaking skills and negotiation skills. Be familiar with your own advantages and the characteristics of the company's products (where are the advantages of other similar products) and accumulate your own customer resources. This will gradually help you get started. Sales all need to do this. Eloquence is honed in actual combat. In fact, goods are distributed.
