What is the summary of chapter 2 in The Oz Principle?

Courage: Individuals and organizations need the courage to face frequent and regular feedback from others in order to recognize behaviors that keep them below the success/failure line (as outlined in Chapter 1). Feedback enables them to take control, address said behavior,  and overcome challenges and obstacles in order to improve. The input of external and impartial parties will allow for a more balanced perception of reality. The more diverse the perspectives sought the better to identify, address and overcome areas for improvement (which keep them below the line). This is framed as accountability.
Heart: Feeling victimized will keep individuals and organizations below the line; as an individual dealing with this, you should identify a situation in which you currently feel victimized. In relation to that situation you should self-assess by listing facts that describe the reasons you feel victimized in such a way that will persuade others of your victim status. Many people will omit their own role (accountable facts) in creating the circumstances in which they then feel victimized. Upon completing the list, you should attempt to focus instead on accountable facts, that is, acknowledge your contributing role. The reader is guided through overcoming this victim cycle in order to find the courage (i.e., heart) to own their circumstances. By accepting the ways in which we create our own circumstances, we can set about overcoming them.
Brains: Finally, in order to overcome your circumstances and move above the line, you must constantly anticipate and identify them and then act with wisdom. The required attitude and behavior can be encouraged by frequent self-reflection in the form of the question “what else can I do?” and then acting upon the outcome. By diligently and persistently addressing this question in thought and action, the individual or organization can move above the line.
