"Live this day as if it will be your last. Remember that you will only find 'tomorrow' on the calendars of fools. Forget yesterday's defeats and ignore the problems of tomorrow. This is it. This is all you have. Make it the best day of your year. The saddest words you can ever utter are 'If I had my life to live over again.' Take the baton, now, Run with it! This is your day! Beginning today, treat everyone you meet, friend or foe, loved one or stranger, as if it were their last moment on earth. Extend to each person, no matter how trivial the contact, all the care and kindness and understanding and love that you can muster, and do it with no thought of any reward. And your life will never be the same again."
