Xenophon

Keep your word and act honorably in agreements; trust is a foundation of both politics and personal life.

Value friendship, hospitality, and reciprocal obligation; civilized life depends on generosity and mutual respect.

Learn from experience, especially hardship; adversity is a teacher that reveals character and sharpens wisdom.

Understand that reputation is shaped by conduct; lasting honor comes from deeds remembered by others.

Use authority justly; good leadership requires fairness, concern for the governed, and attention to the common good.

Seek excellence through habit and exercise; virtue is built through repeated practice, not mere intention.

Train body and mind together; physical endurance, martial skill, and sound reasoning should reinforce one another.

Pursue moderation in all things; excess weakens character, judgment, and discipline.

Respect the gods, tradition, and moral order; human success depends in part on reverence and humility.

Honor loyalty and comradeship; shared struggle creates obligations of mutual support and trust.

Cultivate courage, but pair it with prudence; bravery without judgment is recklessness.

Stay resilient under adversity; endure setbacks with composure, adapt to changing conditions, and keep moving forward.

Prepare carefully and act decisively; success in difficult circumstances comes from foresight, planning, and execution.

Value practical usefulness over abstract display; knowledge should help solve real problems and improve conduct.

Practice disciplined self-control; mastery of appetite, comfort, and impulse is essential to freedom and effectiveness.

Lead by example: a leader must share hardship, take responsibility, and earn trust through action rather than words.
