The mark of mediocrity is to look for precedent.

I have come to believe that a great teacher is a great artist and that there are as few as there are any other great artists. Teaching might even be the greatest of the arts since the medium is the human mind and spirit.

幸福不是拥有你想要的，而是想要你拥有的。

Success is not about the destination, it's about the journey.

我们今天选择的材料将成为我们明天留下的遗产。

Success is not about numbers, it's about touching hearts.
