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.

唯一能给你带来幸福的是你自己。

处于逆境中，就好比周身都扎着针、敷着药；冥冥中却能磨炼人的意志、培养高尚的品行。处于顺境中，就好比被各种各样的兵器包围；冥冥中掏空了身体，消磨了向上进取的意志。

艺术是关于提出问题，而不是提供答案。

Time is the best architect; it allows true architecture to settle.
