Second, people change their jobs all the time, but they do not often change their friends. Most people do not spend their entire career at one company, and even if they do, many of them do not feel the greatest sense of achievement or happiness at their job. However, people tend to have friends from when they were young, and these friends are always there for them during difficult situations. For example, after my cousin graduated from college, she worked at more than five different companies. Although she was a very good employee and was promoted to be the supervisor of her team, she still felt most at home in the company of her friends. She told me that she had three close friends since childhood. She traveled with them during vacations, confided in them, and celebrated life’s moments. These friends have been the source of her happiness her whole life.?
