I came by this interesting "About me" here: http://shuiziliu.com/home/index.php/content/section/9/61.html

    All through your life you will meet people with more talent than you. They may be winners on the ball field, in the classroom or in the workplace. Does this mean you are unable to achieve what they have? Certainly not. You simply have to choose to work harder. Resentment, blame and excuses will only poison your potential.
