"Don't judge a book by its thickness either"

In this quote, "Don't judge a book by its thickness either" by Craig Bruce, the author is expressing a message about not making presumptions based on superficial appearances. The expression "judge a book by its density" is a play on the common saying "Don't judge a book by its cover." It suggests that a person must not make judgments or form opinions entirely based upon the physical density of a book. The quote encourages individuals to look beyond external elements and dive deeper, indicating that real value or worth can not be determined by surface-level observations. It advocates for a more thorough and open-minded technique to understanding and appreciating things in life.
