The superior man understands what is right; the inferior man understands what will sell.

Your eyes are always bigger than your stomach.

It is not the failure of others to appreciate your abilities that should trouble you, but rather your failure to appreciate theirs.

The wise man admires water, the kind man admires mountains. The wise man moves, the kind man rests. The wise man is happy, the kind man is firm.

Rate the task above the prize; will not the mind be raised? Fight thine own faults, not the faults of others; will not evil be mended?

Make fair agreements and stick to them

An angry person is always full of poison.
