I've been reading this book for work. It espoused 4 basic principles to apply at work:
1) Choose your attitude
2) Make their day
3) Play
4) Be there
As I was purusing the BB, it seemed to me that a lot of these principles fit DR too.
We have the ability to make choices about our attitude towards our mates and our Rs every single day when we get out of bed.
We certainly have the ability to make their day, either by giving them something they want, or giving them the space they need to figure out their own way.
We can always play, either by ourselves, with our mates, or with our friends. There's ALWAYS room for fun!
And we can always work on "being there" for our mates by making sure we are focused on what they are saying when they are talking to us and not listening to the TV, the kids, the laundry, the meal, the work we brought home, etc. Being there is about honing listening skills and just "being present" with someone.
I think I would add this book to the list of DR supplementals.
