Bill Bryson said this quote

Take a moment from time to time to remember that you are alive. I know this sounds a trifle obvious, but it is amazing how little time we take to remark upon this singular and gratifying fact. By most astounding stroke of luck and infinitesimal portion of all the matter in the universe came together to create you and for the tiniest moment in the great span of eternity you have the incomparable privilege to exist.For endless eons there was no you. Before you know it, you will cease to be again. And in between you have this wonderful opportunity to see and feel and think and do. Whatever else you do with your life, nothing will remotely compare with the incredible accomplishment of having managed to get yourself born. Congratulations. Well done. You really are special.
