From The Book
It is not the man who has too little, but the man who craves more, that is poor.
Accordingly, some things torment us more than they ought; some torment us before they ought; and some torment us when they ought not to torment us at all. We are in the habit of exaggerating, or imagining, or anticipating, sorrow.
Your greatest difficulty is with yourself; for you are your own stumbling-block.
