The secret to change is the word, because if the word gets into you, it becomes a divine power and a supreme force in you that creates an atmosphere around your life and gives your life divine direction and acceleration!
The success of a man is not by accident. Your life is built by what you expose it to. 
The training you expose and give your mind and body to is what they respond to.
However, the training of your spirit is of utmost importance.
Give yourself training through the spirit to speak the word. The word will teach you how and what to think. Could the book be the words of God, the essence of the secrets of Heaven.
