Let me express my personal feelings: I am also in business. Judging from your description, I haven't really done business yet, and the time is very short. Some jobs are not business at all, like drinks. Without a certain period of unremitting accumulation, it is impossible to make achievements. Personally, I feel that the purpose of doing business is to accumulate resources and funds. Your sister also wants you to hone your ability, be true, but be tactful. For example, if you take that card, you don't understand the needs of leaders. Maybe you look down on other people's practices and complain, but you can't even survive a company. What about the future development?
