Read about how this is actually harmful for long-term motivation though in a book called 59 Seconds with latest psychological research. Basically as kids we are rewarded for doing things like going to school. Good effort on exam and learning = A+. But then carrying into real life that kills our motivation for doing things without the reward (if we're not getting paid for it we must not like it). It also has the opposite affect, if we get a reward for something we don't like doing it either. Maybe people would like doing things more if they got paid less!
