" One reason for this ability to cope with disaster is that nothing ever happens to us except what happens in our minds. Unhappiness is an inward, not an outward, thing. It is as independent of circumstances as is happiness. Consider the truly happy people you know. I think it is unlikely that you will find that circumstances have made them happy. They have made themselves happy in spite of circumstances. "
