The Kingdom of Heaven is within you. - Robert Collier

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, thoughts of wealth, of supply. We must build them in our own mind first.

Dream lofty dreams, and as you dream, so shall you become. Your vision is the promise of what you shall one day be; your Ideal is the prophecy of what you shall at last unveil.

Your chances of success in any undertaking can always be measured by your belief in yourself.
