“Let us not look back in anger or forward in fear, but around in awareness.”
– James Thurber


“Everyone knows what focus is. It is the taking possession by the mind, in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought. Focalization, concentration, of consciousness are of its essence. It implies withdrawal from some things in order to deal effectively with others.”
– William James, textbook Principles of Psychology
