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.

Success is not final, failure is not fatal: It is the courage to continue that counts.

Memory is the only paradise from which we cannot be driven.

We are all creatures of our landscape; it dictates behavior and even thought in the measure to which we are responsive to it.

我总是努力提升自己。
