I don't recall reading any of the "traditional" self help books, but I have read a lot of sales, management, and motivation themed books.
My favorites are the creativity inspiring self help books like "A Kick in the Seat of the Pants" and "A Whack on the Side of the Head" by Roger von Oech and the creative thinking books by Edward de Bono.
