"You are well aware that it is not numbers or strength that bring the victories in war. No, it is when one side goes against the enemy with the gods’ gift of a stronger morale that their adversaries, as a rule, cannot withstand them. I have noticed this point too, my friends, that in soldiering the people whose one aim is to keep alive usually find a wretched and dishonorable death, while the people who, realizing that death is the common lot of all men, make it their endeavour to die with honour, somehow seem more often to reach old age and to have a happier life when they are alive. These are facts which you too should realize (our situation demands it) and should show that you yourselves are brave men and should call on the rest to do likewise." —Xenophon, The Persian Expedition

"Quality is not an act, it is a habit." —Aristotle
