I've now read all of Dani Shapiro's memoirs. Three of them are like this, structured as mini-essays around a theme: marriage, spirituality, and here, writing. Not an instruction manual, rather vignettes about one writer's life. I found it pleasant to read but left with no particularly striking insights.

The one thing I do pick up from Shapiro is that it's okay to write about the same thing more than once. She covers the same incidents and themes over and over again.
