"What you think upon grows. Whatever you allow to occupy your mind you magnify in your life. Whether the subject of your thought be good or bad, the law works and the condition grows. Any subject that you keep out of your mind tends to diminish in your life, because what you do not use atrophies. The more you think of grievances, the more such trials you will continue to receive; the more you think of the good fortune you have had, the more good fortune will come to you."
Emmet Fox from Make Your Life Worthwhile, 1942
