There are three things to beware of through life: when a man is young, let him beware of his appetites; when he is middle-aged, of his passions; and when old, of covetousness, especially.
The small man thinks that small acts of goodness are of no benefit, and does not do them; and that small deeds of evil do no harm, and does not refrain from them. Hence, his wickedness becomes so great that it cannot be concealed, and his guilt so great that it cannot be pardoned.
The superior man, when resting in safety, does not forget that danger may come. When in a state of security he does not forget the possibility of ruin. When all is orderly, he does not forget that disorder may come. Thus his person is not endangered, and his States and all their clans are preserved.
Look closely into his aims, observe the means by which he pursues them, discover what brings him content - and can the man's real worth remain hidden from you?
