Anais on her diaries

She tried to write novels but felt they were flat. With her diary, she learned "how to capture the living moments...that often withered in formal work."

I felt that way about writing personal essays as opposed to poetry. There was never, "the immediate present, the worn, the near, being written at white heat."

That's a good way to say what it is you should be getting at when you write, "a white heat" and "the living moments".
