The desired effect of exercise,as an example,has three possible causes:motivation,willpower,or habit.Though every action is some combination of motivation and willpower,we tend to rely more on one or the other.Then there is that weird hybrid of trying to get motivated while saying you have to do it anyway (it usually comes to this when the battle is lost).
例如，锻炼的预期效果有三个可能的原因：动机、意志力或习惯。尽管每一个行动都是动机和意志力的某种结合，但我们往往更依赖于其中的一种。还有一种奇怪的混合体，一边试图激励自己，一边说你无论如何都要去做（通常是在战斗失败的时候）。
