Anytime you do anything publicly - action, art, ideas, opinions - it becomes open for interpretation. It's just reality. That we need to accept. You have to be prepared for negative and positive responses. The key question then becomes how do you know if you're getting feedback or criticism.
Let's take the worst case - a negative know it all who kills you for just being WRONG offering no additional solution. I'm not saying be that person because your better than that but don't discount it - there is value to be had everywhere. Is it possible, internally you KNEW that action/idea/opinion would offend that type of person? CONFIRMED. Is it possible, you didn't KNOW that action/idea/opinion would offend that type of person? CONFIRMED. Get the point? Viewing it as a GAIN situation is way better than letting it piss you off and put you in the gutter.
So what's the difference between feedback and criticism...
In my eyes not much. It's simply the way YOU hear it.
