Talent renders the whole idea of rehearsal meaningless; when you find something at which you are talented, you do it (whatever it is) until your fingers bleed or your eyes are ready to fall out of your head.

Stephen KingThe workman cut to the left, still laying on his horn, and roared around the drunkenly weaving limousine. He invited the driver of the limo to perform an illegal sex act on himself. To engage in oral congress with various rodents and birds. He articulated his own proposal that all persons of Negro blood return to their native continent. He expressed his sincere belief in the position the limo driver's soul would occupy in the afterlife. He finished by saying that he believed he had met the limodriver's mother in a New Orleans house of prostitution.
