Do answer your letters soon after they are received, and do try to reply to them with some relation to their contents; a rambling, ill-considered letter is a satire upon your education.
Do, when you talk, keep your hands still.
Do observe; the faculty of observation, well cultivated, makes practical men and women.
Do attach as much importance to your mind as to your body.
Do be natural; a poor diamond is better than a good imitation.
Do try to remember where you put your gloves and cardcase; keep the former mended and the latter filled.
Do recollect that your health is more important than your amusements; you can live without one, but you'll die early without the other.
Do try to be sensible; it is not a particular sign of superiority to talk like a fool.
