When stocks are attractive, you buy them. Sure, they can go lower. I've bought stocks at $12 that went to $2, but then they later went to $30. You just don't know when you can catch the bottom.
【译文】如果不明事理,那么动就不知道往哪里去;如果不动,那么即使明白事理也没有用处。
The mind is not a mirror of the world, but an instrument for dealing with it.
