" The battle you wage against your human nature is an invisible one that will be won or lost in the mind. Minute by minute, hour by hour, in the hidden workshop of your mind, you are constructing thoughts of good or evil, depression or joy, success or failure. You are writing your own life story as a human being with each subtle and soundless thought you think. "

― Tommy Newberry , The 4:8 Principle: The Secret to a Joy-Filled Life
