Psychologists have been studying specifically the possible link between persistence and health. On the one hand, it seems that persistence increases the chance you'll succeed in the long term, and that personal success is closely linked to well-being. Think of successful people you know personally, and look back over their lives. Have they always been clear about where they're going in their lives, and now that they have arrived, are they happy and healthy? Some are, perhaps.
心理学家们一直在研究毅力和健康之间可能存在的关系。一方面，长久来看，毅力似乎能够提高人们成功的几率，并且个人的成功与健康息息相关。想想你所了解的成功的人，回顾一下他们的生活。他们一直都很清楚自己人生的走向，并且现在已经成功了，他们是快乐且健康的吗？也许有些人的确是这样的吧。
