William Walker Atkinson 
Nuggets of the New Thought [EPUB ebook] 

From the first chapter: “I Can and I Will‘ — The recognition — Equal to any task — A feeling of calm confidence — An abiding sense of power, reserve force and security — The Something within — The triple key to the door of attainment — The vibrations of Success. ‚I Can and I Will!!!‘ Have you ever said these words to yourself with a firm conviction that you were speaking the truth — with the strong feeling that needed no other proof. If so, you then felt within you a thrill which seemed to cause every atom of your being to vibrate in harmony with some note in the grand scale of Life, sounded by the Real Self.
