Because we don't know when we will die, we get to think of life as an unexhaustable well yet everything happens on a certain number of time, and a very small number, really. 

How many more times will you remember a certain afternoon of your childhood, some afternoon that's so deeply part of your being that you can't ever consider your life without it, perhaps four or five time more, perhaps not even that ? 

How many more times will you watch the full moon rises ? 

Perhaps twenty, and yet it all seems limitless.

Paul Bowles, The Sheltering Sky
