Dr. Peale has written this book for all ""apathetic and unhappy"" people... It's about enthusiasm and let him tell it since it ""makes the difference between success and failure,"" ""is the spice of life,"" needs ""mental ventilation, ""persuades"" and ""cancels fear and worry...tension,"" ""builds power under your difficulties"" All of this with referrals to his own books, to Great Lives such as S.S. Kresge or Calvin Coolidge, and of course to an even higher intervention. Dr. Peale has one chapter on ""What Would An Imaginative Person Do With Your Job?"" H'mmm, he'd be pretty apathetic and unhappy at times.
