If you could only have ONE book in your library, other than the Bible, this would be the book. Honestly, as a minister, I write sermons week in and week out and I keep this book at my elbow for reference. I have hi-lighted, underlined and notated this book through and through. Covey truly hit a home run in distilling seven principle-driven habits that, when applied, can change one's life for the better. Heck, even ONE of these principle, BE PROACTIVE, is enough to change one's life. Do yourself a favor and buy this book then buy a couple more to give away as gifts. In our emasculated culture we men especially need to revisit these seven habits.
