 Learning requires a healthy degree of vulnerability, a willingness to change our minds, to re-examine something we think we've got all figured out and there could be nothing else to learn or say and we can't learn from those people and we can't learn from those people who are not our tribe or not throughout from our group or it's a voice that we're not familiar or comfortable with. I think without a healthy sense of vulnerability we exclude and we remove ourselves from so much learning, so much new information, so much more wisdom than we have.
