The book has opened a world of opportunities that i could not see before. it is practical. everyone can benefit by reading it. the method that the authors describe can be used for any negotiations, from small to big: settling differences in views with your colleagues, talking to your family members, not giving in when a client asks you for an unjustified discount, when your house contractor doesn't want to do the proper job, managing a hostage crisis and even negotiating a nuclear arms deal with another, perhaps narrow minded country.i highly recommend this book for everyone to read. moreover, if you have children who are ready to fly out or recently left your nest- make them read this book because it may change their lives, in a good way.
