he Power of your Subconscious Mind. In Believe in Yourself Dr. Murphy shows you how the power of believing in yourself will help you achieve your dreams. He illustrates his points with wonderful stories about how inventors, writers, artists, and entrepreneurs have used this power to reach the highest of heights. By the end of the book you will have the tools for success. There are many men who quietly use the abstract term success, over and over many times a day until they reach a conviction that success is theirs. As a man repeats the word success to himself with faith and conviction, his subconscious mind will accept it as true of himself, and he will be under subjective compulsion to succeed. - Joseph Murphy
