“Try to understand and remember that a person always tries to do what is best for himself. And if he is right when he does the best thing for himself, it is good; but if he is mistaken, it is bad, because suffering will follow after such mistakes. If you remember this, then you will never be upset by anybody, you will never reproach anybody, and you will never be an enemy to anybody.”

Leo Tolstoy, A Calendar of Wisdom (Page 130)
