mcflog,
Buy the book if you don't already have it.
Study this site ,especially the archives.
Post questions -the AI's on this site are very generous.
Ideally I would recommend an hour with Lynn or Ted.

As for the sales question,TGM as taught by this site ,will only help-probably A LOT.
I am very fortunate to have had the resources to attend several sessions/schools with Lynn,Ted ,VJ and Jeff.Knowing what I know now I would do anything for A 1 OR 2 HOUR LESSON -just to get started on TGM.It would make the journey that much shorter.
However,if you can't do the latter but can afford the first 3 above you will not be succumbing to mere hype .
Good luck
