Swearing immediately evokes aggression. So if you think that cursing shows your enthusiasm and willingness to win, you're wrong.
A team's success is the success of every individual, not just the boss. In many cases, the boss's participation in a success is quite negligible. Your people will always know when you take credit for their achievements.
A certain rivalry in the team can be good, but not to the extent that one day you find your people conspiring against you.
A manager who plays favorites inevitably loses confidence. Moreover, it often happens that these people only take advantage of the manager and when they reach a certain influence, they get rid of him.
Do you think you're funny? Try to find out if others agree. How would you look in a comic sketch in front of an audience that doesn't know you?
Every manager must reckon with the fact that people make mistakes. The important thing is to learn from the mistakes, which can be done much more effectively without shouting and tantrums.
Managerial functions require taking care of your appearance. It's not just about your clothes, but also about how you take care of your hair and beard and about the way you smell. People should not have to hold their noses in your presence because you smell or because of your excessive use of perfume.
Most managers find it difficult not to micromanage their people. You should try hard not to overdo it as well, otherwise others will begin to think that you have nothing else to do.
