" Sometimes when one cannot stand the story or novel one
is working on, it helps to write something else—a different
story or novel, or essays venting one's favorite peeves, or exercises
aimed at passing the time and incidentally polishing up
one's craft. The best way in the world for breaking a writer's
block is to write a lot. Jabbering away on paper, one gets
tricked into feeling interested, all at once, in something one is
saying, and behold, the magic waters are flowing again. Often
it helps to work on a journal, since that allows the writer to
write about those things that most interest him, yet frees him
of the pressure of achievement and encourages him to develop
a more natural, more personal style. "
