In theory， there is no difference between theory and practice; In practice， there is.
Chuck Reid

There are more fools in the world than there are people.
Heinrich Heine

When two men in business always agree， one of them is unnecessary.
William Wrigley Jr. (1861 - 1932)

Happiness is always a by-product. It is probably a matter of temperament， and for anything I know it may be glandular. But it is not something that can be demanded from life， and if you are not happy you had better stop worrying about it and see what treasures you can pluck from your own brand of unhappiness.
Robertson Davies
