The whole universe is change and life itself is but what you deem it - either gratefully better than or bitterly worse than something else that you alone choose.
Marcus AureliusThink nothing profitable to you which compels you to break a promise, to lose your self respect, to hate any person, to curse, to act the hypocrite.
Marcus AureliusThe cucumber is bitter? Then throw it out. There are brambles in the path? Then go around them. That's all you need to know. Nothing more. Don't demand to know "why such things exist." Anyone who understands the world will laugh at you, just as a carpenter would if you seemed shocked at finding sawdust in his workshop, or a shoemaker at scraps of leather left over from work.
Marcus AureliusConsider frequently the connection of all things in the universe and their relation to one another. For things are somehow implicated with one another, and all in a way friendly to one another.
Marcus AureliusDo not act as if you were going to live ten thousand years. Death hangs over you. While you live, while it is in your power, be good.
Marcus AureliusA man should always have these two rules in readiness. First, to do only what the reason of your ruling and legislating faculties suggest for the service of man. Second, to change your opinion whenever anyone at hand sets you right and unsettles you in an opinion, but this change of opinion should come only because you are persuaded that something is just or to the public advantage, not because it appears pleasant or increases your reputation.
