Happy the man, and happy he alone, <br />He who can call today his own: <br />He who, secure within, can say, <br />Tomorrow do thy worst, for I have lived today. <br />Be fair or foul or rain or shine <br />The joys I have possessed, in spite of fate, are mine. <br />Not Heaven itself upon the past has power, <br />But what has been, has been, and I have had my hour.<br /><br />John Dryden<br /><br />http://www.poemhunter.com/poem/happy-the-man-2/
