When I notice something I don't like in other people, I immediately look for that same trait in myself. One reason for this is that I notice how often people criticize others for being some way they themselves are. I don't want to be like that. For example, I know someone who says she hates sneakiness and when people talk about others, but she's the sneakiest, most backstabbing person imaginable. Well, I don't like jealous, control freaks who [archate](http://blog.kentforliberty.com/2016/08/archate.html). So I try to make certain I'm not disliking people who are just like me.
