You are correct that it's not limited to our industry. I run into these kinds of people in many other places in my life. And if I've ever needed to spend any amount of time working with them, I prefer to work alone, interacting only when absolutely necessary. As to Erin Brokovich, she's an excellent example of confidence without ego. It's been difficult for me to cultivate confidence in the presence of others - I was never actually encouraged as a child (sometimes passively discouraged- "why would you want to do that? plenty of other people are doing that.") And apparently it's not common practice to encourage each other as adults.
