The only way to do great work is to love what you do.

When you fail, you learn. When you succeed, you learn even more.

"To be hopeful in bad times is not just foolishly romantic. It is based on the fact that human history is a history not only of cruelty, but also of compassion, sacrifice, courage, kindness."

人生没有绝对的答案，只有不断的尝试。
