given a time machine or 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.
如果能回到过去，她会告诉21岁的自己：一个人的幸福在于他懂得——生活不等于你的收获和成就。你的简历，你的证书并不代表你的生活，尽管很多人会混淆着两者。生活是如此的复杂，任何人都无法掌控它。明白了这一点，你就能够宠辱不惊。
