Excellent resource for understanding the sales process and for preparing very good questions. I also like the fact that it is evidence based selling. I highly recommend it.
The psychology of sales well described harder to implement.
Great book worth every second.
You can hear every mistake you make.
Good for self analysis.
I had a very hard time listening to this audiobook. (monotone) One thing that was very discouraging was that it was all one track. If you could not listen to the whole CD at one time, you can not pick up where you left off or skip to desired tracks. It has a lot of great facts about research on selling but lacks the techniques and information that you would actually use.
