Gail Sher is a master baker, author of the inspirational 'From A Baker's Kitchen', which like the better known 'Tassajara Bread Book' describes less a set of recipes than a way of life.
The same can be said of 'One Continuous Mistake'. With writing as with baking, what is offered is not a set of prescriptive guidelines, for this is not a simplistic 'how-to' manual. Rather this is a highly accessible and attractive collection of insights into what it is to be a writer.
Sher is a member of the San Francisco Zen Center, and her approach is guided by an interpretation of Zen principles. For her, writing, like meditation, is a 'practice'. The path is itself the destination.
I would take issue with the Amazon review posted here, which says, 'Though there are a few writing exercises here, this is less a workbook than a series of meditations on how to be a writer.' Actually there are plenty of 'exercises' if you want them. For instance, the book is particularly helpful in guiding the reader through the writing of haiku (short poems)as a way into writing. Sher's approach is intensely practical. She proposes 'four noble truths' of writing, of which the first is 'writers write'! However, rather than haranguing readers into despair over the paucity of our own written words, she invites us to see how exactly the writing life can become for us immesurably enriching.
Actually, there is another book on a similar theme - writing as interpreted by a Zen perspective - and it's called 'Writing Down The Bones' by Natalie Goldberg. Don't ask me to choose between them. Read them both. After all, writers need all the friends they can get.
