Marketing and sales are about story telling and influencing would be customers, so that they can see a need for the product you offer. For me, I have found the list of books below to be very informative. Note, they are not listed in any particular order. I mostly listen to the audio or mp3 versions, that way i can just play them as i do other things. Most of them have actionable steps and are not just high level talk.
a. Spin Selling by Neil Rackham
b. 50 ScientificallyWays to Be Persuasive by Noah J. Goldstein, Steve J. Martin, Robert B. Cialdini
c. Three Steps to Yes by Gene Bedell; -Only print, no audio
d. Made to Stick: Why Some Ideas Survive and Others Die by Chip Heath & Dan Heath
e. How To Win Friends & Influence People by Dale Carnegie
Heh, I own 4 of those 5 books (not the Gene Bedell one). All are on my "to read" list but other than Spin Selling (which I've browsed through a bit), I haven't read them yet.
I've heard a lot of good things about Made To Stick though, so I think it's time to bump that up the list a little.
