Liked:
Marshall has a Great voice and is inspirering in his stores. I believe NVC us a useful tool to build an strengthen relationships.

Learned:
NVC can in addition to guide how one speaks, guide how one listens And be used when mediating conflicts between others.

Lacked:
Most evidence was anecdotes if the author, or the east experience of the author. I think this kind of claims should include more science.

Longed for:
Though it explains the steps of NVC I think this should go and explain or reference other techniques needed for this to be successful. Perhaps low-arousal approach etc..
