I met a young man who always talked with his head tilted a bit sideways, because somebody once told him he had the profile of a famous actor. Most people didn’t think he had an actor’s profile; they thought he had a screw loose.
This is what happens when making an impression on others determine our actions. It’s human nature to seek recognition for our achievements. Whatever we’re proud of, we want others to know about it, too. Next time you’re in a conversation, see how long it takes the other person (and yourself!) to start mentioning personal accomplishments.
