"Unlike Alice, Garp was a real writer—not because he wrote more beautifully than she wrote but because he knew what every artist should know: as Garp put it, 'You only grow by coming to the end of something and by beginning something else.' Even if these so-called endings and beginnings are illusions. Garp did not write faster than anyone else, or more; he simply always worked with the idea of completion in mind."
~ John Irving, The World According to Garp
