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.

The artist is nothing without the gift, but the gift is nothing without work.

In all affairs， it's a healthy thing now and then to hang a question mark on the things you have long taken for granted.

The only way to deal with temptation is to yield to it.

沒有個人的推動，社會就會停滯。沒有社會的同情，個人的推動就會消失。

Every exhibition should be a question, not an answer.

預測未來的最好方式就是創造未來。

你以為早上醒來昨天就不算數了。但昨天才是真正算數的。
