be optimistic

Optimism is the source of the fun of life。We can take away nothing at death，especially fame and wealth. Although you gain the fame and wealth，you lose the opportunity to experience life. A man can make everyone respect him, not because he is rich or powerful，but can be a life with optimism and vigor. Importantly，he also can influence people around him. we should remember those who smile to you，who encourage you when you are down and out.
