建筑必须灵活才能持久。
Character is doing the right thing when nobody's looking. There are too many people who think that the only thing that's right is to get by, and the only thing that's wrong is to get caught.
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。
