The way NVC has helped me the most is ironically not with conversations with other people but with conversations with myself, and helping me explain to myself why I'm feeling a certain way in response to something. Specifically, what has helped me were the distinctions between feelings and thoughts, and needs being universal while wants are just the ways you try to fulfill a need in a certain moment.

Applying NVC with myself is also a lot less awkward -- with people early on I often overdid it and got a lot of funny looks :) But over time, using NVC primarily to understand a situation, I can pick and choose the way I say it to a person so that person trusts that I'm being genuine instead of just applying a formula.

In my case, the ideas in NVC probably saved my life by giving me a tool to work through several personal crises. In my social group no one really knows NVC or that it's important to me, I often try to be subtle about it. It's fascinating to see it on the front page of HN.

I'd be happy to share my experience with NVC, which I primarily use with myself but often guides my approach to problems at work or with friends.
