在生活中取得成功的方法是既不要抱怨也不要摸索，而是要尝试。

There'll always be serendipity involved in discovery.

Leadership means making tough decisions even when they are unpopular.

The only purpose for which power can be rightfully exercised over any member of a civilized community， against his will， is to prevent harm to others.

我从不回头看。我期待下一个挑战。
