Most people know what playing victim is. If you don't, playing victim is when someone, in whatever situation they are faced with (usually bad), can always find a way to say how they were done wrong. We've all had these moments. When we get all upset about what somebody did to us but we can never see what we might've done to them first. Most of the time it's our pride that causes that to happen.
Before I get deeper into that, let me explain what playing hero is. It's when you end up in a situation and you are convinced that you did the right thing regardless of how it affected anyone else. This is what I caught myself doing before I apologized to my friend. I had that little ugly voice in my head that said, "I did what was right and it doesn't matter how my friend felt because she's wrong and I'm right."
All of that stems from not being humble and having WAY too much pride. Don't get me wrong. There's nothing wrong with being proud of yourself, in fact, everyone (if you think hard enough) has something they've accomplished and should be proud of in their life. However, never forget that overconfidence is all too real and WAY too easy to fall into. In an argument, see yourself in the other person's shoes. How are they feeling? If you don't know, ask. If you're too upset, then tell the person you'll meet back with them in 5 minutes. NEVER EVER just leave an argument. Then, once you've collected yourself ask them the above question. This will prevent you from only seeing how you feel and, therefore, avoiding playing hero or victim. So, go ahead. Let go of your pride and apologize to that person (or people). And remember, stay CONFIDENT.
