As a Man Thinketh by James Allen is a motivating and inspirational book.
I received a complimentary Kindle copy in an Amazon promotion. That did not change my opinion for this review.
I gave it four stars.
"The title comes from the Bible: "As a man thinketh in his heart, so is he." -- Proverbs, chapter 23, verse 7."
