There is an old German axiom which, translated, warns, "Paint the devil on the wall and he is sure to appear;" and another, equally pictorial and memorable: "As you shout into the hills, so the echo returns to you." These truths have meaning to me, for if I think in terms of fear and trouble, my imagination brings forth what I fear. Distrust my fellow man and I will distort him, so that he automatically becomes untrustworthy in my eyes. Shout my pessimism or joy in life into the hills, and as true as I live and breathe, the echo will return to discourage or enhance my days, and speed or block my rhythm of life.
