This book was gifted to me during a pretty complicated time in my life. I can happily and EASILY say that the contents of this book does not have to only be applied in a corporate environment, it can be applied in your day to day life as well. Specially if you have difficult people to deal with.
This book backs simple communication practices that we might overlook as 'mediocre' or too 'time consuming' with scientific research and facts and makes you go "Well then... That explains a lot".
I am happy to say that this book was the beginning of me finding my way out of my 'complicated' situation and into a lifestyle that I am thoroughly enjoying right now. Still to this date (it's been a year now) I practice what I learnt through this book.
I highly recommend that you give this book a go!
