The greatest challenge of our time is not technological advancement, but moral progress.
我们这个时代最大的挑战不是技术进步，而是道德进步。
永远不要让任何人告诉你你做不到某件事。
For every expert there is an equal and opposite expert, but for every fact there is not necessarily an equal and opposite fact.
如果你热爱你的工作，你每天都会出去尽你所能做到最好，很快你周围的每个人都会从你那里感受到激情——就像发烧一样。
