Norman Vincent Peale has lot of encouragements in his book "The Power of Positive thinking". As he said: 'Believe in yourself. Have faith in your abilities. With sound confidence you can succeed.'
That's why he said about the book: 'It teaches positive thinking, not as a means to fame, riches or power, but as a practical application of faith to overcome defeat and accomplish worthwhile creative values in life.
It teaches a hard, disciplinary way of life, but one which offer great joy to the person who achieve victory over himself and the difficult circumstances of the world.' Please read the 'EPILOG' at the end of the book to understand how this book can benefit you most.
