Too desperate for caution
And too broken to care
With a running leap I dove
Head first into the shallow end
Of your “I’m Sorry…”
Try to learn to breathe deeply, really to taste food when you eat, and when you sleep really to sleep. Try as much as possible to be wholly alive with all your might, and when you laugh, laugh like hell. And when you get angry, get good and angry. Try to be alive. You will be dead soon enough.
William Saroyan, The Daring Young Man on the Flying Trapeze (Preface)
Most definitely NOT Ernest Hemingway despite it often being mis-attributed.
