Beware the barrenness of a busy life.
每一本书都是一次旅程，每一次旅程都会改变我们。
把守外海不如把守海口，把守海口不如把守内海。
There is no greater sorrow than to recall happiness in times of misery.
The secret of change is to focus all of your energy，not on fighting the old，but on building the new.
改变的秘诀是集中你的所有能力，不是摧毁旧的，而是建造新的。
"The past is always present, it's just that sometimes it's more present than at other times."
