What Is Mastery?

The sixth chapter of the book is about what mastery means, and all the other five chapters are about how to get there. What mastery means is you've reached a level in your field. And i want to make it clear from the beginning that i am not prejudiced about what field you are in. All levels of human endeavor have a level where you can reach mastery. It's kind of a feeling that's so superior, that so amazing, that it almost eludes language.
