In Part III, the Public Victory section, we'll learn about the relationship bank account and Habits 4, 5, and 6. The key to mastering relationships is first mastering yourself, at least to some degree. You don't have to be perfect, you just need to be making progress. The Public Victory will help you become interdependent, that is, help you learn to work cooperatively with others, so that you can say, "I am a team player, and I have the power to influence and inspire people." This is an even greater accomplishment. The long and short of it is, your ability to get along with others will largely determine how successful you are in your career and your level of personal happiness.
