I heard about this book on James Bryan Smith's "Things Above podcast."
Smith claimed he emptied a highlighter while reading the book.
I emptied two.
Something's changed inside me. Lots to reflect on, and a few reread to come.
I agree with Tim Keller, “I read because I’m desperate.” While reading by itself will not make one a better leader or follower, reading well will improve both. Yet, even then, one must take the knowledge and allow it to change his/her life. Read purposefully.
