It's so easy to get wrapped up in arguing with people. We often feel like someone owes us something, but really we all have done something wrong. The best path is just to avoid treating people poorly. If you want to be treated fairly then it is crucial to focus on building character that is based on treating others fairly. You don't need to hold the door open for everyone, but maybe you can forgive some people who have wronged you in the past. It's not a burden that you should carry. Just rise up and be better than them.
