世界是一场伟大的戏剧，我们是其中的演员。
The world is a great play, and we are the actors.
Success is not final, failure is not fatal: It is the courage to continue that counts.
The beauty of mathematics only shows itself to more patient followers.
企业的边界由一体化成本与市场交易成本之间的权衡决定。
We are healed of a suffering only by experiencing it to the full.
我训练时就像我不是最好的，这样我才能保持最好。
