Some people give up the moment an obstacle is placed in front of them. Some people doggedly continue to pursue a goal even after years of frustration and failure. What is the difference between these two people? Those who feel they are not responsible for choosing their goals and pursing them tend to believe that results are arbitrary. To them, it does not matter how hard you try or how talented you are. Being successful is all a matter of luck. Those who persevere,         , recognize that they are ultimately responsible not just for pursuing their goals, but for setting them. To them, what you do matters, and giving up for no reasons does not seem very attractive.
