Start With Yourself is an instruction rather than a description, and the shelving shows how it means to deliver on it. The catalogue files the book with biographies and memoirs as well as with personal development, which is the signature of writing that uses lived experience as the evidence base for its advice.
Emma Grede reads the work personally, and at nine hours there is room to be both things properly: the account first, then the lesson drawn out of it. Books built this way live or die on specificity, and the length at least gives specificity somewhere to sit.
