Two quotations from St. Augustine:
"Lack of order produces restlessness. Where there is order there is peace."
"You youthful students, must begin by abstaining from sex, from the enticement of gluttony and drunkenness, an immodest concern for body and dress, pointless sports and games, the heaviness of too much sleep and laziness, vain competition, detraction, envy, ambition for status and power, and even from the excessive desire for simple praise. Know that the love of money is the certain ruin of all your hopes. Do nothing willy-nilly, or rashly. Do not get angry at the faults of friends and acquaintances and if you do, swallow your anger, so as not to show it. Refrain from hating anyone. Do not fall into vice of any kind. Do not take excessive vengeance when punishing, or be mean in forgiving. Above all, do not punish unless it is for the sake of improvement, and don’t be lenient on anyone who might get worse by it. Treat those under your authority as if they belonged to your own family. Serve to the extent of embarrassment those who give you orders, and exercise authority so as to make it a delight to obey you. Don’t be unwilling to correct other people’s faults. Avoid enmity most cautiously, bear it most equitably, bring it to an end as fast as possible. In all kinds of dealings with people, keep in mind the popular saying: do not do unto others what you do not wish to be done unto you. Do not aspire to public office before time. Attain the necessary maturity for it before the twenty-fifth year, better if earlier. Should you arrive late to the study of this discipline, do not think yourself exempt from the foregoing advice: it is easier to assimilate it in mature age. Have friends or seek to have them in any circumstance of life, anywhere and at any time. Defer to worthy persons, even though they may not desire it. Ignore the proud, and above all don’t be proud yourself. Live in an orderly and harmonious way. Worship, think about and love God with the support of faith, hope, and love. Pursue peace and due order in your studies, those of your friends and whoever else has talent, with a view to a good mind and a quiet life."
