These towering optimists of 20th century America lived fantastically long lives: NapoleonHill (1883-1970), Norman Vincent Peale (1898-1993), John Wooden (1910-2010), Ronald Reagan (1911-2004).
During the worst year of the Great Depression, 1937, a writer named NapoleonHill picked the theme out of the gutter and lifted the spirits of the country, with a best seller called Think and Grow Rich.
