Deletion of PROUD Principle

Comment: Wikipedia is  for promoting a non-notable book you wrote yourself. In a quick Google search just now, the ONLY reference I found to this principle was the Wikipedia article. As Noah pointed out, the author did a nice job of name-dropping in the article (Maya Angelou was only one of several), but it does not add to the concept's notability
