As a boy, I once saw a cart of melons that sorely tempted me. I sneaked up to the cart and stole a melon. I went into the alley to devour it, but no sooner had I set my teeth into it, than I paused, a strange feeling coming over me. I came to a quick conclusion. Firmly, I walked up to that cart, replaced the melon - and took a ripe one.
Mark TwainIf there is one thing that is really cheerful in the world, it is cheerfulness. I have noticed it often. And I have noticed that when a man is right down cheerful, he is seldom unhappy for the time being. Such is the nature of man.
Mark Twain
