“it makes sense to do something that's tangential to the whole path that you're trying to pursue this goal that you're trying to pursue that is Believe It or Not much worse than just being a motivated and when I say worse I don't mean picking some task that normally you don't like to do but now you're willing to do I mean literally thinking about what would be worse than being in this state again without causing yourself tissue or psychological damage what would be worse well cold water would be worse for many people very cold water”
