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.
如果给我一部时间机器，我会告诉21岁的自己，人的幸福在于知道生活不是一份漂亮的成绩单，你的资历、简历，都不是你的生活，虽然你会碰到很多与我同龄或更老一点的人今天依然还在混淆两者。生活是艰辛的，复杂的，超出任何人的控制能力，而谦恭地了解这一点，将使你历经沧桑后能够更好的生存。
经济学的目标是理解如何以最高效的方式分配稀缺资源。
你在掌控之中，有没有你想去的地方？
坚持非常重要。你不应该放弃，除非你被迫放弃。
心的记忆会消除坏的，放大好的。
I'm not perfect, but I'm always myself.
The absurdity of life doesn't make it meaningless, but rather gives it a special kind of meaning.
