You need to be prepared for firm decisions and action, without losing gentleness towards those who obstruct or abuse you. It's as great a weakness to be angry with them as it is to abandon your plan of action and give up through fear.
Marcus AureliusReflect often upon the rapidity with which all existing things, or things coming into existence, sweep past us and are carried away.
Marcus AureliusSay to yourself in the early morning: I shall meet today ungrateful, violent, treacherous, envious, uncharitable men. All of these things have come upon them through ignorance of real good and ill... I can neither be harmed by any of them, for no man will involve me in wrong, nor can I be angry with my kinsman or hate him; for we have come into the world to work together.
Marcus Aurelius
