I see no reason not to use a journal as, among other things, a commonplace book.
So I'll quote two lines from Le Guin that I particularly like. First, from her Foreword to The Birthday of the World and Other Stories:
To create difference—to establish strangeness—then to let the fiery arc of human emotion leap and close the gap: this acrobatics of the imagination fascinates and satisfies me as no other.
I think that's as good a description as I've seen of what I love so much about her best work.
Second, from one of the stories here, "Solitude":
I never knew anybody, anywhere I have been, who found life simple. I think a life or a time looks simple when you leave out the details, the way a planet looks smooth, from orbit.
