Begin with gentle toils; and, as your nerves 180
Grow firm, to hardier by just steps aspire.
The prudent, even in every moderate walk,
At first but saunter; and by slow degrees
Increase their pace. This doctrine of the wise
Well knows the master of the flying steed. 185
First from the goal the manag’d coursers play
On bended reins; as yet the skilful youth
Repress their foamy pride; but every breath
The race grows warmer, and the tempest swells;
