Regardless of who you are or what you do, you are going to run into (and have to deal with) at least some amount of incompetence in your work life. Why not learn to take it in stride, and not let it bother you so much?
This acceptance of the way things really are will probably allow you to say (or think) something like, “Of course it’s going to be like this from time to time.” Rather than focusing on the most dramatic and extreme examples to validate your belief in rampant incompetence, see if you can recognize and appreciate the fact that most people do really well, most of the time. With a little practice and patience, you’ll cease being so upset over things you have very little control over.
By simply making allowances in your mind for something that is going to happen anyway, you’ll be able to dramatically improve the quality of your life. I know that dealing with incompetence can be frustrating – especially when the stakes are high. I can virtually guarantee you, however, that losing your cool isn’t going to help very much.
The next time you run into incompetence, rather than turning the incompetence into front page news in your mind, see if you can turn it into just another minor story. If you do, you’ll be free from yet another of life’s sources of frustration.
