For some professionals, having contacts is half the business success. Especially for work content with strong social attributes, contacts and resources are important factors to promote business. Therefore, many people are consciously expanding their social circle. Even people who have only met once in a while can't wait to be drawn into their circle of friends. It seems that they have a wide range of friends and can't be used one day.
People who succeed in their careers often endure loneliness and find happiness in those seemingly stylized processes. They are good at self-control and can let time follow their own arrangements.
