Life is half spent before we know what it is.

Do not feel certain of anything.

Live each season as it passes; breathe the air, drink the drink, taste the fruit, and resign yourself to the influences of each.

In a word, each man is questioned by life; and he can only answer to life by answering for his own life; to life he can only respond by being responsible.

Vigor is found in the man who has not yet grown old, and discretion in the man who is not too young.

Your time is limited, don’t waste it living someone else’s life.

The world is a comedy to those that think, and a tragedy to those that feel.

Dying is nothing. What is terrible is not to live.

Nothing exists except atoms and empty space; everything else is opinion.

The weight of this sad time we must obey; speak what we feel, not what we ought to say. The oldest hath borne most: we that are young, shall never see so much, nor live so long.

I often think that the night is more alive and more richly colored than the day.

Great wisdom is generous, petty wisdom is contentious. Great speech is impassioned, small speech in cantankerous.

We should be careful to get out of an experience only the wisdom that is in it—and stop there; lest we be like the cat that sits down on a hot stove lid. She will never sit down on a hot stove lid again—and that is well; but also she will never sit down on a cold one any more.

The man who is truly good and wise will bear with dignity whatever fortune sends, and will always make the best of his circumstances.

Where there is charity and wisdom, there is neither fear nor ignorance. Where there is patience and humility, there is neither anger nor vexation. Where there is poverty and joy, there is neither greed nor avarice. Where there is peace and meditation, there is neither anxiety nor doubt.

A wise man proportions his belief to the evidence.

Wisdom is nothing but a preparation of the soul, a capacity, a secret art of thinking, feeling and breathing thoughts of unity at every moment of life.

In life, all good things come hard, but wisdom is the hardest to come by.
