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.

Believe in yourself even when no one else does.

The mind is nature's answer to the challenges of existence.

你在地球上。对此没有解药。

You are the only one who can make the difference. Whatever your dream is, go for it.
