What is a summary of chapters 3 and 4 in The Oz Principle?

Chapter 3 attempts to define accountability. It discusses the ways that people normally define accountability—as reporting on what they're doing—and how that is ineffective. The author argues that it's confessional and causes people to use excuses rather than to focus on getting results. He says accountability should be redefined as "An attitude of continually asking what else can I do to rise above my circumstances and achieve the results I desire?" It's about identifying and doing the task rather than putting that responsibility on others.
Chapter 4 is about courage and how you have to use it to see things clearly even when times are difficult. Without courage, a person will have a harder time facing facts and doing what needs to be done. Sometimes, having this courage means accepting your imperfections, recognizing them, and working to improve them. The author says that people often fail to see reality because they don't want to change or have the environment around them change. Another issue is that people want to blame their problems and shortcomings on others.
