Let him remember that many before now have tried to chastise a wrongdoer, and failing to punish their enemy have not even saved themselves; while many who have trusted in force to gain an advantage, instead of gaining anything more, have been doomed to lose what they had. Vengeance is not necessarily successful because wrong has been done, or strength sure because it is confident; but the incalculable element in the future exercises the widest influence, and is the most treacherous, and yet in fact the most useful of all things, as it frightens us all equally, and thus makes us consider before attacking each other.
5th-century BC Athenian historian and general
Thucydides (or Thoukydides)(c. 472 BC – c. 400 BC) was an ancient Greek historian, author of the History of the Peloponnesian War, which recounts the 5th century BC war between Sparta and Athens. This work is widely regarded a classic and represents the first work of its kind.

You can now, if you choose, employ your present success to advantage, so as to keep what you have got and gain honour and reputation besides, and you can avoid the mistake of those who meet with an extraordinary piece of good fortune, and are led on by hope to grasp continually at something further, through having already succeeded without expecting it.
Words had to change their ordinary meaning and to take that which was now given them. Reckless audacity came to be considered the courage of a loyal ally; prudent hesitation, specious cowardice; moderation was held to be a cloak for unmanliness; ability to see all sides of a question, inaptness to act on any. Frantic violence became the attribute of manliness; cautious plotting, a justifiable means of self-defence. The advocate of extreme measures was always trustworthy; his opponent a man to be suspected. To succeed in a plot was to have a shrewd head, to divine a plot a still shrewder; but to try to provide against having to do either was to break up your party and to be afraid of your adversaries.
The fate of those of their neighbours who had already rebelled and had been subdued was no lesson to them; their own prosperity could not dissuade them from affronting danger; but blindly confident in the future, and full of hopes beyond their power though not beyond their ambition, they declared war and made their decision to prefer might to right, their attack being determined not by provocation but by the moment which seemed propitious. The truth is that great good fortune coming suddenly and unexpectedly tends to make a people insolent; in most cases it is safer for mankind to have success in reason than out of reason; and it is easier for them, one may say, to stave off adversity than to preserve prosperity.
Fire signals of an attack were also raised toward Thebes, but the Plataeans in the city at once displayed a number of others, prepared beforehand for this very purpose, in order to render the enemy's signals unintelligible, and to prevent his friends from getting a true idea of what was happening and coming to his aid before their comrades who had gone out should have made good their escape and be in safety.
