If you are preparing to write a story on how you grew up in South Dakota, before your parents moved to California and you eventually ended up in Maryland, this book might have good tips for your memoires.
The book is designed for beginners and gives tips on how people should write without editing so that they keep on writing, then how they should learn editing to improve their writing skills, and finally how to write with love and emotions, a tip that cannot apply to all kinds of writers.
So if you are writing on that cookies recipe you came up with, or the memorable trip you made to the Bahamas, buy this book.
But if you are more of a professional writer looking to publish a book on your experience in civil, military or diplomatic service, then you might a more serious text book for better advice.
Also the style of the book is probably designed for sixth graders, with exercises and examples of fake journals.
