R. H. Jarrett

Roy Herbert Jarrett, a Chicago salesman and ad man — distills the positive-thinking enterprise into a (deceptively) simple exercise of itemizing your desires in a list in It Works!. Jarrett produced just one additional book, The Meaning of the Mark (1931), which extrapolates on the methods and ideas behind his shorter pamphlet.
