My favorite quotes from this piece about what motivates writers who relate personal stories in their writing are :
Making art is all about humans and our psychology: who we are, how we behave, what we do with the hand we’ve been dealt. It’s closer to your own bone when it’s a memoir, but the bone is still the bone.
More and more I feel there’s no contradiction and no delineation between my domestic life and my creative life. One can’t exist without the other. There is this life and there is this driving need to dive into that place that then expands, and that world is as large and encompassing when I’m inside it as the world that’s all around me.
