决定我们成为什么样人的，不是我们的能力，而是我们的选择。

So given a Time Turner, I would tell my 21-year-old self that personal happiness lies in knowing that life is not a check-list of acquisition or achievement. Your qualifications, your CV, are not your life, though you will meet many people of my age and older who confuse the two. Life is difficult, and complicated, and beyond anyone’s total control, and the humility to know that will enable you to survive its vicissitudes.

Success is not about the money you make, it's about the difference you make in people's lives.

A person may cause evil to others not only by his actions but by his inaction， and in either case， he is justly accountable to them for the injury.

世界是一个舞台，我们都是演员。

书是一份你可以反复打开的礼物。

城市是最伟大的建筑作品。

质量不是一种技术，而是一种哲学。
