You may fetter my leg, but Zeus himself cannot get the better of my free will.

The greater the difficulty the more glory in surmounting it. Skillful pilots gain their reputation from storms and tempests.

Anything worth putting off is worth abandoning altogether.

Control thy passions lest they take vengence on thee.

Freedom isn't the right or ability to do whatever you please. Freedom comes from understanding the limits of our own power and the inherent limits set in place by nature. By accepting life's limits and inevitabilities and working with them rather than fighting them, you become truly free.

Is freedom anything else than the power of living as we choose? Nothing else. Tell me then, you men, do you wish to live in error? We do not. No one who lives in error is free. Do you wish to live in fear? Do you wish to live in sorrow? Do you wish to live in tension? By no means. No one who is in a state of fear or sorrow or tension is free, but whoever is delivered from sorrows or fears or anxieties, he is at the same time also delivered from servitude.

We do not choose our own parts in life, and have nothing to do with those parts. Our duty is confined to playing them well.
