"The key to innovation is diversity of thought."

我在你们这个年龄，最害怕的不是贫穷，而是失败。

Don't be afraid to make mistakes. If you're not making mistakes, you're not trying hard enough.

Human kindness has never weakened the stamina or softened the fiber of a free people. A nation does not have to be cruel to be tough.

如果没有正确应用的智慧，最先进的技术也毫无用处。
