Lily is talking to her singer friend, Chad.
L: Chad, what a lucky guy you are!
C: What do you mean?
L: Well, you've got everything a person could ask for: a lovely family, money and fame.
C: Nothing's as wonderful as it seems.
L: But such a successful man as you must surely be happy.
C: Not really, I'm so busy that I don't live a n.mp3al life.
L: Anyway, I wouldn't mind being in your shoes.
C: And I would love to be able to live as simple a life as you do.
L: I guess you should never judge a book by its cover.
C: How right you are!

by = according to
Sometimes we can see someone well-dressed, but he could be a crook.
Don't judge a book by its cover. 勿以貌取人
