Every condition, every experience of life is the result of our mental attitude. We can do only what we think we can do. We can be only what we think we can be. We can have only what we think we can have. What we do, what we are, what we have, all depend upon what we think. We can never express anything that we do not first have in mind. The secret of all power, all success, all riches, is in first thinking powerful thoughts, successful thoughts, and thoughts of wealth, of supply. We must build them in our own mind first.
