I think sure-headedness is a sign of a closed mind. Think about it. When someone says they're absolutely positive about something, they are often so because they don't want to take the time to listen or see another person's perspective. Their mind is made up and that's all there is to it. I see this all the time and it's a huge problem.
Am I right? I'm absol--I'm sure of it.
