On Keeping a Notebook by Joan Didion (PDF)
But our notebooks give us away, for however dutifully we record what we see around us, the common denominator of all we see is always, transparently, shamelessly, the implacable “I.” We are not talking here about the kind of notebook that is patently for public consumption, a structural conceit for binding together a series of graceful pensees; we are talking about something private, about bits of the mind’s string too short to use, an indiscriminate and erratic assemblage with
meaning only for its maker.
A wonderful essay about the what and why for the author, Joan Didion, of keeping a notebook. Which may be different than the what and why you may have. And it is a point she writes so eloquently about here.
I may have to copy this whole delicious thing into my commonplace book.
