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.
I am dragged along by a strange new force. Desire and reason are pulling in different directions. I see the right way and approve it, but follow the wrong.
Cunning leads to knavery. It is but a step from one to the other, and that very slippery. Only lying makes the difference; add that to cunning, and it is knavery.
While strength and years permit, endure labor; soon bent old age will come with silent foot.
[Lat., Dum vires annique sinunt, tolerate labores.
Jam veniet tacito curva senecta pede.]
