Life teaches us not to regret over yesterday, for it has passed and is beyond our control. Tomorrow is unknown, for it could either be bright or dull. So the only alternative is work hard today, so that we will enjoy a better tomorrow.

人生教会我们不要对过去的事感到后悔，因为过去的终究是过去了并且我们已无法控制。没人知道明天会是怎样，因为它可以是光明的同样也可以是无趣的。所以，唯一的选择便是在今天努力工作，这样才能让我们去享受更美好的明天。
