Going to work not only brings us earnings, it also helps us to improve our social life. First and foremost, you cannot work in a major company by yourself because we need numerous people to maintain a company with multiple positions. Therefore, building relationships with your co-workers is needed to support you in different aspects of work. For example, if you have a project with your team, and to have higher-quality of work, all members will support each other with their strengths, thus, you can gain your skills by learning from others' experiences. Moreover, if you decide to work alone in a company, your work performance will decrease as you do not have the chance to improve your expertise because it is usually learned from other employees. Consequently, this means it might take you a large amount of time to finish your work, which could lead you to bad mental health.
