The important thing in life is to have a great aim, and the determination to attain it.人生重要的事情是确定一个伟大的目标，并决心实现它。

Life can only be understood backwards, but it must be lived forward. 回首才能懂得人生，但人生却必须继续向前走下去。

All that you do, do with your might; things done by halves are never done right.做一切事都应尽力而为，半途而废永远不行。
