“Be more concerned with your character than your reputation, because your character is what you really are, while your reputation is merely what others think you are.”
This one is simple and to the point: what others think can never dictate the type of person you are. People may not think the best of you, but if you are satisfied with your own life and believe yourself to be successful.. then who the hell cares? You will always be your strongest critic anyway, so focus on making yourself happy. The rest doesn’t matter.
