If you're like most Americans, your motivation at work (or in other areas of your life) is likely tied to rewards that aren't completely related to your actions. You work forty hours a week for that Friday afternoon paycheck, instead of for a job well done. You promise yourself a new wardrobe as a reward for losing weight or giving up smoking, instead of relishing your healthier body. You work hard in school, or motivate your children to work hard in school, for the sake of earning high grades, not for the sake of learning new skills.
