Stop this mental exhaustion; you're already doing great. Are you constantly agonizing over something, unable to figure it out during the day, unable to sleep at night, feeling physically and mentally exhausted even though you haven't done anything wrong? This is a classic example of mental exhaustion. Psychology says that excessive thinking isn't being diligent, but rather self-destructive. You're always concerned about others' opinions, afraid you're not doing enough, afraid of being rejected, but you forget that life isn't about pleasing everyone. Stop dwelling on your minor flaws, stop worrying about things that haven't happened yet, and stop punishing yourself for others' mistakes. Allow yourself to make mistakes, allow things to be imperfect, allow everything to take its natural course. You don't need to be perfect, just be authentic and free. Let go of your obsessions, stop this self-inflicted torment, and you'll find that living easily is more important than anything else.
