I have now but one anxiety left, which is concerning you. I would have you be, what I know nobody is, perfect. As that is impossible, I would have you as near perfection as possible. I know nobody in a fairer way toward it than yourself, if you please. Never were so much pains taken for anybody’s education as for yours; and never had anybody those opportunities of knowledge and improvement which you have had, and still have. I hope, I wish, I doubt, and I fear alternately. This only I am sure of, that you will prove either the greatest pain, or the greatest pleasure of, Yours Always Truly.

Lord Chesterfield (1694-1773) English statesman, wit [Philip Dormer Stanhope]

Letter to his son, #141 (16 Feb 1748)
