GETTING MORE has all the essential negotiation techniques for all aspects of your life: work, home, relationships, kids, & more. It‘s a tome at almost 400 pgs; however, the steps are fairly simple & you aren‘t learning 400 pages worth of information. Instead, Diamond teaches through repetition and anecdotes that show practical usages of the the Getting More model in every situation you can imagine.
