I've just read Nonviolent Communication a Language of Life by Marshall Rosenberg. This is a book I should have read many years ago but I couldn't because it just came out in 2003. There are many excellent books on good communication. Many cover the same territory as Rosenberg covers but Rosenberg has made the message more concise and practical. After you read this book you will have some practical things you can use.
Rosenberg covers four areas: Giving form the heart, Compassion, observing without evaluating and identifying and expressing feelings.
I was a teacher and every day I saw how important good communication was. The more accurate and particular you were the more successful things were..
You had to watch your students for cues from them as to how they were feeling and how they were reacting. Sometimes missing a clue could make a big difference. I asked all my classes to watch what I did when I first came in the classroom. They really didn't know so after some prompting they saw what I was doing. I made sure that I looked at every student to see if there were any clues I should pick up from them. This made sense to the kids. I also suggested that they do the same for me. Check me out. Am I in a bad mood?
Sometimes dealing with parents required care or you could end up in a nasty conversation. Looking back at some difficult interviews usually showed that I missed something.
So Rosenberg's book puts things in a format the is practical. If you follow his ideas you can avoid some nasty communications problems and solve problems once you're in them. He gives examples with students, couples, staffs and street groups.
So if you like books on communication, this is a good one.
