Conversation should touch everything but should concentrate itself on nothing.
对话应当面面俱到,无所不谈,但又不可深谈。
Courtesy costs nothing. Lower the toilet seat after use. Let the people in the elevator exit before you enter. Return shopping carts to their designated areas. When you borrow something, return it better shape (filled up, cleaned) than when you got it.
设定一个野心得荒谬的目标的好处是,上限足够高,这样即使最后失败了,以通常的标准来衡量也可以算某种程度上的成功。
