He worked and trained his whole life
Why did he work so hard his whole life?
He wanted to be the best.
When people work hard, they feel that they are part of something bigger than themselves. Hard work combined with the desire to achieve, determination, and always being motivated to get after your goal makes success feel bigger.
My problem is that the entire population is divided.
I can understand how divisions in the population can make you feel discouraged, but it would still be good to follow this other man's example and really work to better yourself.  Even if others treat you unfairly, many more will notice your talents and reward them.
