Friendship is the only thing in the world concerning the usefulness of which all mankind are agreed.

Interpretation
Familiarity can lead to complacency and a lack of inquiry into the nature of things.
Cicero's quote highlights how repeated exposure to certain sights or experiences can dull our sense of curiosity and wonder. When we become accustomed to something, we often stop questioning its existence or understanding its significance, which reinforces a passive acceptance of our surroundings rather than an active engagement with the world.

She knows, now, absolutely, hearing the white noise that is London, that Damien's theory of jet lag is correct: that her mortal soul is leagues behind her, being reeled in on some ghostly umbilical down the vanished wake of the plane that brought her here, hundreds of thousands of feet above the Atlantic. Souls can't move that quickly, and are left behind, and must be awaited, upon arrival, like lost luggage.
A man is like a fraction whose numerator is what he is and whose denominator is what he thinks of himself. The larger the denominator, the smaller the fraction.
