According to McKinsey, people usually remember one, two, three, but not four, five, six, so everything should be summarized in less than three. This is now widely circulated in the business world "30 seconds elevator theory" or "elevator speech".
Strictly speaking, entering the workplace is the only way to really enter the society, not only to deal with work tasks, but also to deal with all kinds of interpersonal relationships.
Colleagues should be cooperating with each other, not competing with each other as "enemies". If you think of your coworkers as stumbling blocks to your own development, it will be difficult for you to gain a foothold in the office, and of course, it will be even more difficult for you to develop. Remember that mutual benefit is the basic prerequisite for collective acceptance.
