People who will not learn

I speak at many conferences. I see a real difference between the attitudes I encounter. The psychographics of each conference are different. All too often I see people who are convinced that they have nothing to learn from anyone else. They will ask for introductions, but never for other help. I see that these people succeed at a far lower rate, but they rarely change. I suspect that most people acquire this attitude at a very early age and rarely change.
