Leave other people's mistakes where they lie.

It is within our power not to make a judgement about something, and so not disturb our minds; for nothing in itself possesses the power to form our judgements.

People generally despise where they flatter, and cringe to those they would gladly overtop; so that truth and ceremony are two things.

In man's life, time is but a moment; being, a flux; sense is dim; the material frame corruptible; soul, an eddy of breath; fortune a thing inscrutable, and fame precarious.

For a man can lose neither the past nor the future; for how can one take from him that which is not his? So remember these two points: first, that each thing is of like form from everlasting and comes round again in its cycle, and that it signifies not whether a man shall look upon the same things for a hundred years or two hundred, or for an infinity of time; second, that the longest lived and the shortest lived man, when they come to die, lose one and the same thing.

Dig within. There lies the wellspring of good.

The perfection of moral character consists in this, in passing every day as the last, and in being neither violently excited nor torpid nor playing the hypocrite.
