however, that the animal cannot attain top
speed till after it has undergone this severe
discipline.

In training for a contest an athlete usually
takes long runs. Soon after the start he feels
weary and exhausted, but, by disregarding this
feeling and continuing to run, a sudden change
comes over him commonly known as ``getting
his second wind.''

Thus the runner feels wave upon wave of
exhaustion followed by waves of invigoration.
Had he stopped when he first began to tire,
he never would have known of his wonderful
reserve fund of strength which can be drawn
upon only by passing through the feeling
of exhaustion. He seems to be able to tap
deeper and deeper reservoirs of strength.

_Many men have never discovered their reserve
stores of strength because they have formed the
fixed habit of quitting at the first access of weariness_.

Thus they never become conscious of the
wonderful resources which might be used if
they were willing to disregard the trifling
wave of weariness.
