Here’s a quick one for you: Think through all the really obnoxious things you’ve done in your past. If you’re like me, most of them were because you were trying to impress people and/or compensate for some insecurity you had. Looking at your behavior objectively, you now could say, “Yes, I agree that that guy [girl] looks like a real jerk, but I know what I was worried about at the time, and that came off way worse than I meant it. If people who saw that behavior could know the full story, they would have a much better opinion of me.”
OK, now that you’ve finished that exercise, think about all the people you can’t stand because they act like such jerks.
