每个数学问题都有解决方案，但并非每个解决方案都显而易见。

Never confuse movement with action.

听我说话就像一场头脑旅行，因为我只给你那些你和朋友在客厅里开玩笑的东西。

We must listen to science, but also to communities—real solutions are found at the intersection of data and human need.

There is no reason why good cannot triumph as often as evil. The triumph of anything is a matter of organization.

做出伟大工作的唯一方法就是热爱你所做的事情。

听我说话就像一次头脑旅行，因为我只给你那些你和朋友在客厅里开玩笑的东西。唯一的区别是我有胆量在你们面前说出来。

我从不考虑过去。我总是期待下一个挑战。
