I just finished reading Verbal Judo: The Gentle Art of Persuasion. It is a very fast read, and it reminds me of another book that I had read in the past, specifically Way of Aikido: Life Lessons of an American Sensei. Both books deal with applying martial arts concepts to everyday life situations. This book had a few more acronyms and process enumerations, but it was a rather easy read. Definitely a recommended read.
Update: Changed Verbal Judo book link due to broken link on original site.
