The Power of Positive Thinking by Norman Vincent Peale
This book suggests techniques and give examples which demonstrate that you can never be defeated by anything, that you can have peace of mind, improved health and a never ceasing flow of energy. In short, your life can be full of joy and satisfaction.
Science has also verified that this book's basic concept is -- being optimistic makes you healthier and happier and thus more likely to succeed is true to a certain extent. The best quote from the book is, "Action is a great restorer and builder of confidence. Inaction is not only the result, but the cause, of fear. Perhaps the action you take will be successful; perhaps different action or adjustments will have to follow. But any action is better than no action at all."
