Life just isn't fair, is how it used to strike me. Some people can work their butts off and never get what they're aiming for, while others get it without any effort at all. [...] I think this viewpoint applies as well to the job of the novelist. Writers who are blessed with inborn talent can freely write novels no matter what they do--or don't do. Like water from a natural spring, the sentences just well up, and with little or no effort these writers can complete a work. Occasionally you'll find someone like that, but, unfortunately, that category wouldn't include me. I haven't spotted any springs nearby. I have to pound the rock with a chisel and dig a deep hole before I can locate the source of creativity. [...] But as I've sustained this kind of life over many years, I've become quite efficient, both technically and physically, at opening up a new hole in the rock and locating a new water vein. As soon as I notice one water source drying up, I can move on right away to another. If people who rely on a natural spring of talent suddenly find they've exhausted their only source, they're in trouble.
In other words, let's face it: Life is basically unfair. But even in the situation that's unfair, I think it's possible to seek out a kind of fairness. Of course, that might take time and effort. And maybe it won't seem to be worth all that. It's up to each individual to decide whether or not it is.
