From what I know Seth initially learned out method (and we still have a few testimonials from him on our website), then started blogging about it, and now offers some educational materials on it.

@Duane Alexander Some ways I've helped people in the past start building credibility is characteristic testimonials.

There are tons of horror stories, forums, testimonies and every other form of information illustrating what you have here.

Testimonials and Fact Sheets are what resonated with people most... 

As a qualified newbie with only 1 property under my belt, your testimony is inspiration and ironically the start off story for many.

As with most bills, by the time it goes through the end of the congressional process things are changed quite a bit.

Getting testimonials and referrals from people that have already worked with them will be huge. 

The letter then talks about the risks of using a discount broker, all the ways the agent can net the homeowner as much or more than a discount broker, makes an irresistible, completely risk free offer for a “Free Home Audit” and a “Free Special Report”.The agent also uses a few great testimonials and statistics about their success (proof).

Ignore them. ..When you start getting there, the only ones you can get the "you done well" pat on the back are from are the other entrepreneurs........ "  Any corporate type is gonna think you're crazy, that or say "I wish I could do that"Great way to put it with the chic example: no frame of reference.The testimonies of other successful real estate investors are the frames of reference that wholesaling, lease options, flipping,buy & hold etc can be done profitably,safely etc 

Both of those men are gurus in the yellow letter business but a lot of testimonials from their perspective comes from mailing millions of letters out.
