As someone in a community where NVC is highly valued, I agree with this. I think there are some standard good principles out there that are non-specific to NVC, but many of the people who study NVC seem to have their equal share of problems those who don't, and those who don't still have their fair share.

There are many "systems" of communication. Another one is the book Crucial Conversations and many online courses. Similar, there are some things that will work everywhere, but a lot that doesn't seem to go so smooth.

There are certain other things that pretty much universally help (listening to another person, for instance). Not being aggressive with your words, keeping yourself calm.

The best luck I've seen is learning a style of communication and then sharing it with those who matter.
