It's funny to even try and think what success means, given that success only has meaning in the future. I sometimes think of life as a very long proposed logical proof where each step depends on a a step later then it by one tick of the clock. And as time goes by it's continually reduced, a step at time, and eventually we will come to reveal its basis, somewhere out in the future, which is probably is logical false, and will unravel the original proposition, like it never existed in the first place (ie we all die in the end).

Maybe that's all we are, anyway, pieces of a logical computation, which trying to determine something, some solution to a problem that was proposed at the beginning of life on this planet...
