I woke up as the sun was reddening; and that was the one distinct time in my life, the strangest moment of all, when I didn't know who I was - I was far away from home, haunted and tired with travel, in a cheap hotel room I'd never seen, hearing the hiss of steam outside, and the creak of the old wood of the hotel, and footsteps upstairs, and all the sad sounds, and I looked at the cracked high ceiling and really didn't know who I was for about fifteen strange seconds. I wasn't scared; I was just somebody else, some stranger, and my whole life was a haunted life, the life of a ghost.
Beyond work and love, I would add two other ingredients that give meaning to life. First, to fulfill whatever talents we are born with. However blessed we are by fate with different abilities and strengths, we should try to develop them to the fullest, rather than allow them to atrophy and decay. We all know individuals who did not fulfill the promise they showed in childhood. Many of them became haunted by the image of what they might have become. Instead of blaming fate, I think we should accept ourselves as we are and try to fulfill whatever dreams are within our capability.
Second, we should try to leave the world a better place than when we entered it. As individuals, we can make a difference, whether it is to probe the secrets of Nature, to clean up the environment and work for peace and social justice, or to nurture the inquisitive, vibrant spirit of the young by being a mentor and a guide.
