One major disagreement I have with the author is that LIFE IS A MARATHON and not a series of sprints as he suggests. His assumption is wrong and that's where his model crumbles like a cookie. In real life, we experience constant stress; it's the same experience we have running a marathon. We have a goal, we pace ourselves, we hydrate and nourish, we dig deep, and finally go for the finishing kick! That's how we want to live our lives. We want to win and everybody loves a winner!
There's no real sense of victory in sprints, only a fleeting rush of adrenaline. A lot of factors can influence how and when we finish a sprint. These factors can spell the difference of a few milliseconds. But a marathon is brutally frank. You either finish it or you don't; it's up to how much you've trained for it and how much you really want it. Pure guts and glory, and no excuses. That's what life is, isn't it?
