There is also a future, but there is not an old saying: 36 lines, no face. No matter what line of work you are in, you will succeed as long as you work hard. Customer service can actually exercise a person's eloquence. When your professional ability reaches a certain time, you will grow into a group leader, a monitor, a section chief and a manager. Don't try to succeed step by step. Your leadership is also made step by step from what you are doing now, so you can succeed as long as you work hard.
