Thaddeus Kosciuszko

I only became aware of Kosciuszko via kmk, but this "advice to youth" is insightful as to the means for right living:

To do honor to your family and yourself and at my recommendation, you must reread what follows every day so that it will be engraved on your memory on which your well being will depend.

Rise at four in the summer and six in the winter. Your first thoughts must be directed towards the Supreme Being; worship Him for a few minutes. Set yourself to work with reflection and intelligence, either at your prescribed duty carried out in the most scrupulous manner, or perfect yourself in some science in which you should have true mastery. Avoid lying under any circumstances in your life, but always be frank and loyal and always tell the truth. Never be idle but be sober and frugal even hard on yourself while indulgent to others. Do not be vain nor an egotist. Before speaking or answering on something, reflect and consider well in order not to lose your point and say something stupid. Never fail to give due recognition under any circumstances to the person who is in charge of your well being. Anticipate his desires and his wishes. Pay close attention with proper humility. Look for an opportunity to be useful. As you are a foreigner in the country, redouble your concern and efforts to gain trust and preference over the natives legitimately by your merit and superior knowledge. If a secret is entrusted in you, keep it religiously; in all your actions you must be upright, sincere and open; no dissimulation in your speech, do not argue but seek the truth calmly and with modesty, be polite and considerate to everyone, agreeable and obliging in society, humane and helpful to the unfortunate according to your means. Read instructive books to embellish your mind and improve your spirit. Do not degrade yourself by making bad acquaintances, but rather those with high principles and reputation thus your conduct should be such that the whole world approves it and that wherever you may be it will be considered irreproachable.

I don't know if I can get up that early, though....
