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.
Tempore difficiles veniunt ad aratra juvenci;
Tempore lenta pati frena docentur equi.
In time the unmanageable young oxen come to the plough; in time the horses are taught to endure the restraining bit.
The mind is sicker than the sick body; in contemplation of its sufferings it becomes hopeless.
[Lat., Corpore sed mens est aegro magis aegra; malique
In circumspectu stat sine fine sui.]
