Failure gave me an inner security. Failure taught me things about myself that I could have learned no other way. 失败使我的内心产生一种安全感。失败让我看清自己，这也是我通过其他方式无法体会的。I discovered that I had a strong will, and more discipline than I had suspected; I also found out that I had friends whose value was truly above the price of rubies.我发现，我比自己认为的，要有更强的意志和决心。我还发现，我拥有比宝石更加珍贵的朋友。The knowledge that you have emerged wiser and stronger from setbacks means that you are, ever after, secure in your ability to survive.从挫折中获得智慧、变得坚强，意味着你比以往任何时候都更有能力生存。You will never truly know yourself, or the strength of your relationships, until both have been tested by adversity. Such knowledge is a true gift, for all that it is painfully won, and it has been worth more to me than any qualification I ever earned.只有在逆境来临的时候，你才会真正认识你自己，了解身边的人。这种了解是真正的财富，虽然是用痛苦换来的，但比我以前得到的任何资格证书都有用。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.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。Life is difficult, and complicated, and beyond anyone's total control, and the humility to know that will enable you to survive its vicissitudes.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。
