It’s broken into three parts or “books”. Book one is The Amateur Life, book two is Self Inflicted Wounds, and book three is The Professional Mindset. Pressfield says that he can “divide [his] life into two parts: before turning pro and after. After is better.” This book, through a series of short vignettes (often only a part of a page long) that make up each “book”, helps you explore the mindset of an amateur, what we do as amateurs and what we do to stay amateurs…and how we break out – and turn pro. A couple of quick quotes give you a glimpse of the essence of this book. “Becoming a pro, in the end, is nothing grander than growing up”, and a favorite of mine… “The amateur tweets. The pro works.”
Turning Pro is well worth the read, and if you intend to be a professional writer (of any genre), I recommend this book.
