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.
The cruelest part of the workplace development process is that while you understand the cruelty of these rules through all the experiences you go through, you still have to choose to adapt to it.
