How barbarous, to deny men the privilege of pursuing what they imagine to be their proper concerns and interests! Yet, in a sense, this is just what you are doing when you allow your indignation to rise at their wrongdoing; for after all, they are only following their own apparent concerns and interests. You say they are mistaken? Why then, tell them so, and explain it to them, instead of being indignant.
Marcus AureliusCan we wonder that men perish and are forgotten, when their noblest and most enduring works decay? Death comes even to monumental structures, and oblivion rests on the most illustrious names.
Marcus AureliusPeople who labor all their lives but have no purpose to direct every thought and impulse toward are wasting their time-even when hard at work.
Marcus AureliusMost of what we say and do is unnecessary: remove the superfluity, and you will have more time and less bother. So in every case one should prompt oneself: 'Is this, or is it not, something necessary?' And the removal of the unnecessary should apply not only to actions but to thoughts also: then no redundant actions either will follow.
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.
Marcus Aurelius
