keeping a notebook

In “On Keeping a Notebook,” Joan Didion writes, “How it felt to me: that is getting closer to the
truth about a notebook.” Write an essay that interprets what you think the truth is about why
Didion keeps a notebook.
Didion never explicitly says why she keeps a notebook, but in her essay, she does offer many
different reasons for writing. Therefore, you need to interpret those reasons to make an
argument for the main, implied reason that Didion keeps a notebook (or writes), and then prove
that to your reader using evidence from the text.

I am also including my notes on the reading too. It has my interpretation for conclusion.
