Every poem is a small revolution.
生命太短暂，不能活在他人的梦想里。
数学真理是普遍而永恒的。
爱是一切的关键。
Gratitude turns what we have into enough.
You’ve got to have models in your head. And you’ve got to array your experience—both vicarious and direct—on this latticework of models. You may have noticed students who just try to remember and pound back what is remembered. Well, they fail in school and in life. You’ve got to hang experience on a latticework of models in your mind.
