Don’t consent to be hurt and you won’t be hurt – this is a choice over which you have control

You ought to choose both physician and friend, not the most agreeable, but the most useful.

Do you know that disease and death must needs overtake us, no matter what we are doing?... what do you wish to be doing when it overtakes you?... If you have anything better to be doing when you are so overtaken, get to work on that.

Don't explain your philosophy. Embody it.

Practice yourself, for heaven's sake, in little things, and thence proceed to greater.

If thy brother wrongs thee, remember not so much his wrong-doing, but more than ever that he is thy brother.

If evil be spoken of you and it be true, correct yourself, if it be a lie, laugh at it.
