Do you know the difference between love and obsession?

"Let us imagine an individual trying to perform some simple manual task -

 - say, grab an object which repeatedly eludes him;

the moment he changes his attitude, starting to find pleasure in just repeating the failed task,

squeezing the object

which, again and again, eludes him,

he shifts from desire to drive."

 - Slavoj Žižek, The Parallax View (2006)
