应对不自由世界的唯一方法是变得如此绝对自由，以至于你的存在本身就是一种反叛。

Liberty is the fruit of thought.

Leadership is about making tough decisions and standing by them, even when they are unpopular.

The only person you should try to be better than is the person you were yesterday.

Psychology must be purely experimental and analytical.

我相信掌握别人已经摸索出的最佳方法是一门学问。我不相信只是坐下来自己空想。

最终，我们都必须面对自己行为的后果，无论我们多么努力地避免它们。
