失败使我的内心产生一种安全感，这是我从考试中没有得到过的。失败让我看清自己，这也是我通过其他方式无法体会的。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。
Failure gave me an inner security that I had never attained by passing examinations. Failure taught me things about myself that I could have learned no other way. 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.

在真实与不真实之间，在真实与虚假之间，并没有严格的界限。
If you never want to be criticized， for goodness' sake don't do anything new.
最大的风险就是不冒任何风险。在一个快速变化的世界里，唯一注定失败的策略就是不冒险。
