Much of the difference that I see is attitude, but some of it is tactics. The attitude difference is important for status reasons: others may be much more willing to listen to a "let's figure out what went wrong" than a "listen harder." The tactics difference is in trying out more angles of approach, as well as trying to figure out how what you said sounds to others, like you've done recently. Changing presentation errors is often as useful as changing factual errors.

Would more be helpful, or do you think that's enough?
