没有人能在相当长的时间里，对自己戴一副面具，对大众戴另一副面具，而最终不困惑于哪一副才是真实的。
No man, for any considerable period, can wear one face to himself and another to the multitude, without finally getting bewildered as to which may be the true.
Today was good. Today was fun. Tomorrow is another one.
学无止境的人比无所不知的人做得更好。
实现明天的唯一限制将是我们今天的疑虑。
The only limit to our realization of tomorrow will be our doubts of today.
