Reminds me of words from Mary Schmich's famous "Sunscreen" column (https://www.chicagotribune.com/columns/chi-schmich-sunscreen...): "... Sometimes you're ahead, sometimes you're behind. The race is long and, in the end, it's only with yourself."
Not sure whether I agree with you and her or not. Yes, the race is damned long and I recognize that it is ultimately only with myself. On the other hand, much like trying to beat your own high score, it can be kind of fun and, perhaps more realistically, like many I have nothing better to do.
