Once upon a time, I received an email. When I read it, I thought it said my sky was falling. Then I stopped and asked myself a series of questions to take my emotions out of the issue. It turned out that my sky was not falling, that the person sending me the email was under stress and had expressed their stress (with a situation that did not involve me) in their choice of words in the email they sent me.
If this has ever happend to you, either in an email, a conversation, or a business meeting, I suggest that your first step is to acknowledge your emotional response internally.
Whoa! Why has this statement upset me? What emotion am I feeling AND WHY?
You already know that your internal physical response to stress is not beneficial to your longterm health and happiness. You owe it to yourself, your career, and your long term goals to take these few seconds to monitor and understand why statements upset you. The more you understand about your behavior, the stronger you become.
