"Polish your skin to protect against the meaningless dander that sets to soak in. For your skin is tougher than advanced math with a layer of Hebrew underneath. So when the people you consider dandruff take bites at your peace, they leave their teeth instead of a piece. Never Let Anyone Steal Your Joy!"
Understand that life isn't fair and, in general, people don’t have common sense. With that said, one should expect a fair share of disappointment, embarrassment, and failure in their lives. Everyone experiences those things in various forms and degrees, but the fact of the matter is that nobody is above anyone else. Nobody is perfect and when someone tries to focus on the elements of your imperfection, you realize the issue is their imperfection, not yours. Don’t allow someone else's flaws to penetrate your peace.
