回首才能懂得人生

The important thing in life is to have a great aim, and the determination to attain it.人生重要的事情是確定一個偉大的目標，并決心實現它。

Life can only be understood backwards, but it must be lived forward. 回首才能懂得人生，但人生卻必須繼續向前走下去。

All that you do, do with your might; things done by halves are never done right.做一切事都應盡力而為，半途而廢永遠不行。
