I just remembered a book I came across in college. I highly recommend that everyone read it, but not until after they graduate high school (otherwise fewer people would care about graduating high school). It's called The Underachiever's Manifesto is very small 4 by 6 inches and only 96 pages. It's a very fast and enjoyable read.

EDIT: Your comment reminded me of this book because I want my children to read it someday (but I don't want them to get the attitude too early)...
