so much so that, thanks to this constant work of mental
preparation, when he was back leading his armies there was
simply nothing that could happen that he didn’t know how
to deal with.
Another thing a ruler must do to exercise his mind is read
history, in particular accounts of great leaders and their
achievements. He should look at their wartime strategies and
study the reasons for their victories and defeats so as to avoid
the failures and imitate the successes. Above all he must do
what some great men have done in the past: take as model a
leader who’s been much praised and admired and keep his
example and achievements in mind at all times. Alexander
the Great, it seems, modelled himself on Achilles, Caesar on
Alexander and Scipio on Cyrus. Anyone who reads Xeno-
phon’s life of Cyrus will see how valuable his example was to
Scipio, and how closely Scipio’s decency, charm, humanity
and generosity conform to the description Xenophon gives of
Cyrus. A sensible leader must follow this advice and never
relax in peacetime but work hard to make the most of it and
turn it to his advantage in the tough times ahead. That way,
when his luck does turn, he’ll be ready.
