I was just going to make my vision about the salesletter, and then I asked my self "hum why not to go to see the result".
and I found this :
The Gary Halbert Letter
it is realy interesting.
however, the crazy damned genius don't give any argument on the copy he revealed the secret that induce to phone call.
and the result as pointed in the link above is a success.
but honnestely, I found my self in many of those who thinked that it was not a good letter, but then I thinked a lot about this:
why it was a success.
I think that it is about a good human nature knowdlege.
to be the costumer imply Empathy, and not self projection.
perhaps the true rich are those who spend less.
and may be cliché sell.
again human nature.
