He [Kim Jong Un] wrote me beautiful letters. And they're great letters. We fell in love.

I have been constantly telling people to encourage people, to question the unquestioned and not to be ashamed to bring up new ideas, new processes to get things done.

In Science, it is when we take some interest in the great discoverers and their lives that it becomes endurable, and only when we begin to trace the development of ideas that it becomes fascinating.

Other tasks and other jobs changed, which enabled us to create new jobs that paid more and have fewer of the older jobs that went away. I hope what happens as we lead through this is that there will be pluses and minuses, but the net ends up being even more people because we have more ideas of how to grow.

Knowledge is merely brilliance in organization of ideas and not wisdom. The truly wise person goes beyond knowledge.
