Configure org-mode. I use ~/org as my org directory and hide emphasis markers because it's much easier to read that way. I enable org-crypt to allow reading and writing encrypted org files. I also replace bullets in bulleted lists with nicer looking icons. I configure faces to default to variable-width font, but switching to monospace where it is necessary. Finally, I use visual-fill-column to make org files display with a relatively narrow window centred in the frame.
