Good, simple writing often goes unnoticed or looks easy, since it "gets out of the way" and doesn't confuse. It can take a whole lot of writing on one's own to appreciate just how much patience and effort that takes, though.

Someone posted this quote by Edsger Dijkstra yesterday: “Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better.”
