Jim Cellini's Plagiarism?

What did legendary Street Magician Jim Cellini steal when he wrote his memoir/manual titled "Dreamer's Highway"?

  In the tradition of book publishing, following in the footsteps of S.W. Erdnase, Cellini borrowed major ideas and large blocks of copy from earlier books. As a door to door salesman in his youth, Cellini had evidently been well trained in sales and motivation.

 A classic text on self-help and entrepreneurship is Napoleon Hill's "Think and Grow Rich." Hill ostensibly derived wisdom about wealth building by studying the business leaders of his time.

In the introduction to "Think and Grow Rich," Hill teases the reader by stating that the book contains a valuable secret, hidden in plain sight, and repeated several times. He encourages the reader to celebrate their epiphany once they recognize it. Cellini's "Dreamer's Highway" contains the exact same hook in the introduction. Throughout the text, one of Hill's famous quotes is rephrased and reiterated in several ways. 

According to one of his stories, Cellini used the quote as an answer when people asked him whether his lignum vitae magic wand had real powers. "What the mind can conceive and believe, it can achieve." The OG Professor of Magic, Harlan Tarbell, wrote about magic being the power of the mind to change reality. Cellini extended that philosophy by reminding us that The Wand is the means by which Mind affects Reality-- the real power of Magic.
