Oneguine wanting what he has not.

from Eugene Onegin by Alexander Pushkin fiction ~1 min read

But my Oneguine the whole eve
Within his mind Tattiana bore,
Not the young timid maid, believe,
Enamoured, simple-minded, poor,
But the indifferent princess,
Divinity without access
Of the imperial Neva's shore.
O Men, how very like ye are
To Eve the universal mother,
“Possession hath no power to please,
The serpent to unlawful trees
Aye bids ye in some way or other—
Unless forbidden fruit we eat,
Our paradise is no more sweet."

—Alexander Pushkin, Eugene Onegin, p. -1
