Boredom: the desire for desires.
Anna Karenina, Leo Tolstoy
Boredom is just the reverse side of fascination: both depend on being outside rather than inside a situation, and one leads to the other.
On Photography, Susan Sontag
"Your true traveller finds boredom rather agreeable than painful. It is the symbol of his liberty - his excessive freedom. He accepts his boredom, when it comes, not merely philosophically, but almost with pleasure.”
