Accustom yourself not to be disregarding of what someone else has to say: as far as possible enter into the mind of the speaker.
Marcus AureliusDo not disturb yourself by picturing your life as a whole; do not assemble in your mind the many and varied troubles which have come to you in the past and will come again in the future, but ask yourself with regard to every present difficulty: 'What is there in this that is unbearable and beyond endurance?'
Marcus AureliusNature has given to each conscious being every power she possesses, and one of these abilities is this: just as Nature converts and alters every obstacle and opposition, and fits them into their predestined place, making them a part of herself, so too the rational person is able to finesse every obstacle into an opportunity, and to use it for whatever purpose it may suit.
Marcus AureliusDoes what's happened keep you from acting with justice, generosity, self-control, sanity, prudence, honesty, humility, straightforward ness, and all other qualities that allow a person's nature to fulfill itself? So remember this principle when something threatens to cause you pain: the thing itself was no misfortune at all; to endure it and prevail is great good fortune.
Marcus Aurelius
