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.
The hunter follows things which flee from him; he leaves them when they are taken; and ever seeks for that which is beyond what he has found.
[Lat., Venator sequitur fugientia; capta relinquit;
Semper et inventis ulteriora petit.]
