Of course, there is a certain difference between a manager and a managed roommate. I believe that most people will be adults, and many managers are indeed better than the managed. After all, managers used to be managed, and there is no way to stand out where there is no light.
Therefore, most people also want to work hard and make progress, from a managed person to a manager. To tell the truth, this should be the common idea of most people, and I am no exception. On the other hand, in a sense, the manager's job is much easier and more interesting than that of the managed.
So what kind of characteristics can people become managers? First of all, I think a manager must have quite excellent professional skills, because managers are higher than ordinary employees, so if employees have problems, the first person to turn to is their immediate manager.
The second is that as a manager, you should have certain management skills, including the ability to handle things, the ability to unite teams, good communication skills, the ability to coordinate teams and assign tasks. This ability may be innate, but most of it is acquired.
After that, I think it is the ability to resist pressure and face difficulties. These, because managers actually bear more than ordinary employees, they will directly face all kinds of pressures and situations, which requires a good comprehensive quality, so this is also the reason why managers are better than ordinary employees.
To sum up, I think a manager should have the qualities.
