Was "Think and Grow Rich" Plagiarized? - Side by side comparison of Napoleon Hill and WWA's Work

"Think and Grow Rich" is probably the most widely known, famous book in the areas of personal development and success.  But where did these ideas come from?

It appears as if we have some very peculiar similarities between these two authors' work.  I do a side-by-side comparison of the chapter names.  Did Napoleon Hill really get his ideas from interviewing 100's of millionaires or rather from studying William Walker Atkinson?  I will let you decide.
