About 20 years ago I read a non-business book that says a lot about business. It was called “Getting the Love You Want” by Harville Hendrix. I don’t remember most of it, but there is one sentence that has stayed with me.
He said something like, “Usually what you criticize about others is something you are doing yourself.”
That has turned out to be remarkably true. Whenever I criticize someone else for talking too much or talking too loud or complaining too much or being too dramatic, I realize that this is something that I’ve done myself.
The next time you criticize someone at work, write it down. Then think about if that behavior is something you do. Your criticisms of others may very well be clues into understanding and improving your own behavior.
