翻译：物质的富足填补不了精神的空虚，真正的富有是内心的充盈，知足方能常乐。
浅陋的人，不能和他谈论深奥的见解；愚蠢的人，不能和他谋划有智慧的事。井底之蛙，不能和它谈论东海的快乐。
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.
