Is it profitable to do sales?

Actually, I can't give you a specific answer. I can only say that sales are very profitable, but it is difficult to make money. Sales have to be honed slowly by time, whether it is interpersonal relationship or my own behavior, etc. In short, I generally won't make money in a short time, but as long as I persist, I usually make money, and sales is the most trained industry. Needless to say, there used to be many bosses in China who started their sales. Our boss used to be a salesman, but now he has started his own company. Don't give up as long as he is sure. Maybe he didn't make any money in the first two years, or even lost money at first, but this is the foundation. Because in sales, you have to get through the relationship first, so you have to treat people and give gifts, so you have to pay money first to get income. Generally speaking, I think sales is a very promising job. Come on, if you think the answer is ok, please give me the best answer, hehe.
