Take this at least, this last advice, my son:
Keep a stiff rein, and move but gently on:
The coursers of themselves will run too fast,
Your art must be to moderate their haste.
Adde, quod ingénues didicisse fideliter artes Emollit mores, nec sinit esse fervos. To be instructed in the arts, softens the manners and makes men gentle.
Sleep, rest of nature, O sleep, most gentle of the divinities, peace of the soul, thou at whose presence care disappears, who soothest hearts wearied with daily employments, and makest them strong again for labour!
