This is by far the worst book I have ever read. Do not buy this book. Save yourself the 1.65 and the time. In this book Peale uses faulty induction and touts that his method of positive thinking is "scientifically proven". This guy should go back to grade school and study the principles of induction and re-read the definition of science. Science is based on empirical data, in other words things that can be quantified, observed, or measured. Additionally I highly doubt that God, being the 'all-knowing' god he is, would care how "big", as Peale puts it, your prayers are. The bottom line is Norman Vincent Peale is off his rocker and the only reason he sold 2 million copies, if you can believe him on that, is because of those moronic religious saps that fill up the 'red states'. Those people will buy anything if they think it will get them into heaven.
