"When any person harms you, or speaks badly of you, remember that he acts or speaks from a supposition of its being his duty. Now, it is not possible that he should follow what appears right to you, but what appears so to himself. Therefore, if he judges from a wrong appearance, he is the person hurt, since he is the person being deceived. For if anyone should suppose a true proposition to be false, the proposition is not hurt, but he who is deceived about it. Setting out, then, from these principles, you will meekly bear a person who reviles you, for you will say upon every occasion, “it seemed so to him”."
"When you do anything from a clear judgment that it ought to be done, never shun the being seen to do it, even though the world should make a wrong supposition about it; for, if you don’t act right, shun the action itself; but, if you do, why are you afraid of those who censure you wrongly?"
"Throughout the day, continually pay attention to the way you make value-judgements and respond to your thoughts. Be mindful, in particular of the way you respond to strong emotions or desires. When you experience a distressing or problematic thought, pause, and tell yourself: “This is just a thought and not at all the thing it claims to represent.” Remind yourself that it is not things that upset you but your judgements about things. Where appropriate, rather than being carried away by your initial impressions, try to postpone responding to them for at least an hour, waiting until your feelings have settled down and you are able to view things more calmly and objectively before deciding what action to take."
"The only safe harbour in this life’s tossing, troubled sea is to refuse to be bothered about what the future will bring and to stand ready and confident, squaring the breast to take without skulking or flinching whatever fortune hurls at us."
