I have to take 100 steps

Another mental game I use is to consider Sisyphus, the damned Greek who for all eternity had to roll a boulder up a hill, only to have it roll back down to be rolled up again. He’s the inventor of hill repeats. I take stock of everything that is going on at that low moment, the pain, the frustration, the sluggishness, the hunger, the thirst, and ask myself, If this was what I was doomed to do for all eternity under these circumstances, would it really be that bad?
