Should nurses switch to sales?

Not in sales. In fact, the sales pressure is great and there is no guarantee. You haven't studied systematically at all. If you really start selling, you will be very depressed. Sales is the ability to learn and cultivate slowly. I'm sure I can't adapt to staying in an institutional hospital for so long. If you feel that your present job is not satisfactory, think about what you want, work hard silently, cultivate your hobbies and read more books, which will make you love life more.
