Writing became such a process of discovery that I couldn't wait to get to work in the morning: I wanted to know what I was going to say.

O’Brien describes writing not as the transcription of already-formed ideas but as an exploratory act that generates thought. The excitement of “can’t wait to get to work” frames composition as a daily experiment: the page becomes a site where the writer discovers what she thinks, feels, or knows only by attempting to articulate it. The second clause—wanting to know what she was going to say—captures the paradox of creative work: the author is both the agent and the audience of her own unfolding meaning. The quote also implies a disciplined practice (morning work) in which curiosity, rather than certainty, drives productivity.
