Only free peoples can hold their purpose and their honor steady to a common end, and prefer the interests of mankind to any narrow interest of their own.
A mature person has the integrity to stand alone. And when a mature person gives love, he or she gives without any strings attached to it. When two mature persons are in love, one of the great paradoxes of life happens, one of the most beautiful phenomena: they are together and yet tremendously alone. They are together so much that they are almost one. Two mature persons in love help each other to become more free. There is no politics involved, no diplomacy, no effort to dominate. Only freedom and love.
Don't ever forget that you're a citizen of this world, and there are things you can do to lift the human spirit, things that are easy, things that are free, things that you can do every day: civility, respect, kindness, character.
