——〈建国方略之一：孙文学说——行易知难〉，1919年5月20日

"The beauty of computational complexity lies in its ability to classify problems based on their inherent difficulty."

The past is never dead. It's not even past.

The brave may not live forever, but the cautious do not live at all.

The future is not fixed; it is something we can shape with our knowledge and actions.

译文：该放手的时候必须放手，能够饶恕别人就要饶恕别人。赏析：人生没有两全其美的事，懂得取舍，不失为君子风度。人都有犯错的时候，只要不触碰做人的底线，宽恕别人就是善待自己。
