For many years in the world of psychology, the widely accepted theory has been that our willpower – our self-control – is limited.If we are not careful, we can use up our willpower before a task is completed or before a goal is reached. Psychologists who believe that willpower is a limited resource say using up our willpower is the main reason some of us fail to achieve our goals.___________________________多年来在心理学界人们广为接受的理论是,人们的意志力(即自我控制)是有限的.如果不够谨慎,完成一项任务或者达成一个目标之前就可能耗尽意志力. 坚持意志力有限观点的心理学家表示,耗尽意志力是未能达成目标的主要原因.____________________________
