An old magazine article about the actor Matthew McConaughey (maybe in the NYT?) mentioned that he carries a tape recorder in his car and talks to it on long drives. Interestingly enough he's recently written an autobiography, which he says sprang from his habit of keeping diaries. He says he's kept diaries for 36 years. A "learn by talking" and "learn by writing" person, surely.
