“Someone has said that world history must from time to time be rewritten. When has there been an epoch that made this as necessary as does the present one? You provided a superb example of how it should be done. The hatred of the Romans for the victor, even when he was kindly, presumption upon outmoded privileges, the desire for a different state of affairs without having anything better in view, irrational hopes, haphazard undertakings, alliances with no prospect of benefit, and whatever else is the unhappy retinue of such times—you have described all that magnificently, proving to us that such things really happened in those days.”

Book 7; Variant translation: No enterprise is more likely to succeed than one concealed from the enemy until it is ripe for execution.
Nothing is of greater importance in time of war than in knowing how to make the best use of a fair opportunity when it is offered.
Few men are brave by nature, but good discipline and experience make many so.
Good order and discipline in an army are more to be depended upon than ferocity.
As translated by Neal Wood (1965)
The Art of War (1520)
Context: No proceeding is better than that which you have concealed from the enemy until the time you have executed it. To know how to recognize an opportunity in war, and take it, benefits you more than anything else. Nature creates few men brave, industry and training makes many. Discipline in war counts more than fury.
