How can you expect the absolute highest level of performance from the people around you if you don’t first expect it from yourself?
Everyone sees through the guy who screams at the people around him over everything, they see that he doesn’t hold himself to the same standard he demands of others, they see that he doesn’t hold himself responsible, and they see his sloppiness.
All of that leads to a general lack of respect which people are usually too afraid to vocalize because he’ll flip out and you’ll lose your job and also, he doesn’t accept responsibility so there is a near-zero percent chance that he will ever change.
You can’t change him, but you change you. Hold yourself to a higher standard and I’m going to work on holding myself to a higher standard as well.
