Quote from : Stay Book

People can attach themselves to something--an idea, another person, a desire--with an impossibly strong grip, and in the case of restless ghosts, a grip stronger than death. Will is a powerful thing. Will--it's supposed to be a good treat, a more determined and persistent version of determination and persistence. But will and obsession--they sit right next to each other. They pretend to be strangers and all the while meet secretly at midnight." -
