14．What motivates（激发） us to take on life's challenges？Is it money，fame，power，or something else？Most businesses operate today on the carrot-and-stick system of rewards（奖赏） and punishments．Employees are rewarded for good performance，and punished for performing badly．This usually works well in situations where workers are performining simple tasks，like cheching products or packing boxes．
However，for jobs that repuire creativity，such as writing or designing，it's a different matter．In actual fact，people in these jobs are not so much motivated by outer factors like cash rewards．They do their job because they like it．They like the challenge of it，they like the mastery of it，they like the creativity that it requires．These factors are generally called inner motivators，which can be further broken down into autonomy，mastery and purpose．
Autonomy refers to self-direction．The greatest things that have happened in all kinds of societies--western，eastern，modern，ancient-have been the result of people being able to do what they wanted to do．People，like these Iranian portesters in July 2009，follow the human nature to resist（抵制） control and direct their own lives．
Mastery is the desire to become better at something that matters．A recent Harvard business school research shows that the biggest motivator at work by far is making porgress．People，making progress one day，are more likely to be motivated to make greater progress the next day．
And finally，purpose，to do what we do in service of something larger than ourselves．It is not necessarily something like reducing-green-house gases from the atmosphere，but can be simply writing a great story that helps people understand world a little bit better or creating something that brings beauty to somebody's life．
Today's business managers，facing the increasingly competitive pressures of a global marketplace，should question their traditional attitudes about what actually motivates us as humans．
