Being offended by criticism, you weaken and, exhausting force, you get dependent on these people. Willing to do anything to deserve their good treatment, you're doomed to think of them. And if they praise you, you will carry water for them. If the script gets complicated, the bad will hurt you, and you will serve the good.
Is there anything more noble and difficult than taking a grip on oneself and repentance?
You say that you're not guilty? - Maybe... However, all of us are more or less guilty of something. It's not difficult to find reasons for repentance. What's difficult is swallowing pride and getting over fears and stupidity.
