What are some books that will expand our mind?

Alice's Adventures in Wonderland "I don't much care where –" said Alice. "Then it doesn't matter which way you go," replied the Cat.

Rich Dad, Poor Dad. While this book needs to be taken with a grain of salt this is the book that can change your life, especially if you read it before you are 30.
