Who said it could not be done? And tell me what great victories does he have to his credit which qualifies him to judge what can and can't be accomplished.

Definiteness of purpose is the starting point from which one must begin.

I know that I have the ability to achieve the object of my Definite Purpose in life, therefore, I demand of myself persistent, continuous action toward its attainment, and I here and now promise to render such action.

You might well remember that nothing can bring you success but yourself.

Lack of persistence is one of the major causes of failure. Moreover, experience with thousands of people has proved that lack of persistence is a weakness common to the majority of men. It is a weakness which may be overcome with effort.

Everyone enjoys doing the kind of work for which he is best suited.

What you think, so you will become.
