Yeah, I like the way it was put by Clarence Darrow:
"We are born and we die; and between these two most important events in our lives more or less time elapses which we have to waste somehow or other. In the end it does not seem to matter much whether we have done so in making money, or practicing law, or reading or playing, or in any other way, as long as we felt we were deriving a maximum of happiness out of our doings."
And a similar thought by Will Rogers:
"We are all here for a spell; get all the good laughs you can."
I used to fret over the state of the world, and what it would be in the future, but now I've realized that I can only affect, if anything, the near future. Anything beyond that is not my responsibility, since I can have no effect on it. In a million years (or probably much less time) the very fact of my having ever existed will be completely forgotten, and I might as well have never been at all, for all the effect my life will have had on that furture world. And a million years is as an eye-blink in the long stretches of cosmological time. Only the here/now has any real meaning for me, and the farther I try to look ahead, the less meaning I can see related to my actions.
