This isn't a cryptic goodbye letter to HIVE is it? :P
When people are passionate, they often let their emotion come through with them, instead of letting it stay at the door. They need to suspend that emotion in order to be able to receive pragmatic and balanced feedback (not criticism) of their idea.
Criticism is easy, feedback is much harder.
It's also a two way street. If I am giving feedback, and it is not being accepted, is it because I am trying to then "own" or "morph" the idea? I would hope that the other person clarifies their position and their goals.
Working with others can be difficult, but as long as the goals are aligned, there's an opportunity. If the goals aren't aligned - that is when there is going to be a problem.
