The cause of success is some power within you; you have the power to develop any power to a limitless extent; for there is no end to mental growth; you can increase the strength of this power indefinitely, and so you can make it strong enough to do what you want to do, and to get what you want to get; when it is strong enough you can learn how to apply it to the work, and therefore, you can certainly succeed.
