Has much to say or little, if he cares about writing at all, he will appreciate the pleasures of composition.）（67.To sit at one's table an a sunny morning, with four clear hours of uninterruptible security, plenty of nice white paper, and a Squeezer pen--- that is true happiness. ）The complete absorption of the mind upon an agreeable occupation--- what more is there than to desire?
