"You don't have to be perfect to be amazing."

Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding.

Every stroke, every breath, every moment is a step closer to your goal.

最多人的最大幸福是衡量对与错的标准。

We’re here to put a dent in the universe. Otherwise why else even be here?

成功不是幸福的关键。幸福才是成功的关键。

最高尚的快乐是理解的喜悦。
