Off we go, then.
Well, I'd never heard of this one: the 10th best-selling title of all time. I suppose it doesn't surprise me that a self-help manual would make the top-ten; for obviously these sorts of book sell by the barnload. And two things endeared me to this title straight away. One, the author's superbly-formed imperial tumulus of a name. 'Climbing the Napoleon Hill' is, I think we can agree, a euphemism to conjure with. Then I chanced upon this:
The secret of achievement was tantalizingly offered to readers of Think and Grow Rich, but it was never explicitly identified. Hill felt discovering it for themselves would provide readers with the most benefit.By gum it's true!
The secret to which I refer has not been directly named [in this book], for it seems to work more successfully when it is merely uncovered and left in sight, where THOSE WHO ARE READY, and SEARCHING FOR IT, may pick it up. This is a touch of such genius I feel the impulse to get out of my chair and salute it. The plan is: to put on sale a book called Think and Grow Rich, to be bought by people who hope to become rich, such that the inside portion of the book is given over to saying, in effect, 'you want to become rich? My advice is to think how to become rich, and then do that.' Ian McKellen would be pleased.
Anyway, the text is available online: you can see for yourself.
