最终，我们只会后悔没有抓住的机会。
"In the end, we only regret the chances we didn't take."
The more we realize our minuteness and our impotence in the face of cosmic forces, the more astonishing becomes what human beings have achieved.
If you want something you’ve never had, you must be willing to do something you’ve never done.
〈军人精神教育〉，在桂林对滇赣粤军的演说，1921年12月10日
永远不要让恐惧决定你的未来。
