If you are struggling with taking things personally, I encourage you to employ the tactic of asking yourself "this person is showing me a flaw about themselves. What is it?" None of us are perfect, but we are all human.
Now, I realize that by writing this article, I am (ironically) telling you what to do. So, I'll end with a caveat. If you want to write an article telling other people what to do, I can't stop you. I just wonder if it's worth it.
