Never stop learning because the world never stops changing.
永远不要停止学习，因为世界永远不会停止变化。
The greatest rewards come from working on something that nobody else is working on.
History is, above all else, the creation and recording of that heritage; progress is its increasing abundance, preservation, transmission, and use.
The power of the mind is immense, and harnessing it can lead to profound changes in our lives.
