Say 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.

The wrongdoer is often the person who left something undone, rather than the person who has done something

Do not be wise in words - be wise in deeds.

Be not unwilling in what thou doest, neither selfish nor unadvised nor obstinate; let not over-refinement deck out thy thought; be not wordy nor a busybody.

Do not waste what remains of your life in speculating about your neighbors, unless with a view to some mutual benefit. To wonder what so-and-so is doing and why, or what he is saying, or thinking, or scheming -- in a word, anything that distracts you from fidelity to the ruler within you -- means a loss of opportunity for some other task.

Do not be ashamed of help.

Perfection of character is this: to live each day as if it were your last, without frenzy, without apathy, without pretence.
