A cheery relaxation is man's natural state, just as nature itself is relaxed. A waterfall is concerned only with being itself, not with doing something it considers waterfall-like.
Vernon HowardA chief cause of unhappiness is what I call mental movies. Mental movies are a misuse of the imagination. You know how it goes. You have a painful experience with someone, then run it over and over in your mind. You visualize what you said, what he did, how you both felt. As awful as it is, you feel compelled to repeat the film day and night. It is as if you were locked inside a theatre playing a horrible movie.
