I have worked in a hair salon for four years, so I should sum up what I have learned in these years and whether I have my own skills. Sometimes I don't have to be a boss or start a business. I have technology, I believe you will have old customers, and then a whole set of what kind of technology, what kind of equipment, what kind of service attitude, location and so on. Even if you work for a long time, you should learn to sum up what are the bad places and good places. When you rest by yourself, everything is a kind of growth.
