We are all prisoners of our own minds, and it is only through self-reflection that we can break free.
《在陆军军官学校开学典礼的演说》（1924年6月16日）

Freedom is not given, it is taken.
The past is never truly past; it lives inside us.
The core of drones is not how high they fly, but how well they are used.
做出伟大工作的唯一方法就是热爱你所做的事情。
