I don't think I've read an entire book for pleasure in years. I've read a small number of complete books and very large chunks of textbooks for school purposes though. Most of my leisurely reading consists of reading stuff on the internet, such as
CF.
I would recommend the book "Getting to Yes" by Fisher and Ury. I had to read it for class, but it was a very good book that has influenced my thinking not only in regards to negotiations, but also politics and the approach I take to debate on
CF. It is available for next to nothing on half.com.
