A memoir is a historical account or biography written from personal knowledge and sources. It's a book about your life, the lessons learned, and specific moments that shaped who you are.
We all typically think of a memoir and cringe a little at the idea of a book about someone else's life. But that's not all a memoir is.
It's like the highlight reel from your diary about the experiences that shaped your story.
And even though you're technically writing a nonfiction book, memoirs should be more in the category of fiction when it comes to the style and flow of the book. It's an entertaining read fashioned like a story - it just so happens to be based on actual events.
