You were aware of nothing before you were born, but that thought does not cause you anxiety. Why then should the thought of death bother you? It is merely a return to the state you were in before you were born.

The point is to make yourself part of an historical continuum that extends from your ancestors, through you, and onward. The story is passed to us from our forefathers. We add our few pages, and then we pass it on to those who come after us. Make your contribution the best it can be. Do not squander your time in useless worrying.

Don't cry because it's over, smile because it happened. :-)
