真正的风险来自于不知道自己在做什么。

The past is a source of knowledge, and the future is a source of hope. Love of the past implies faith in the future.

The world, as a rule, does not live on beaches and in country clubs.

The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.

忠于自己，但始终乐于学习。

爱的奥秘比死亡的奥秘更伟大。
