The author of the article also says he sometimes starts over. That his first attempts just explore the problem domain. There was a post about Jon carmack throwing out some "gross" code because as he worked on it he found the true crux of the problem and it reduced the complexity significantly. Almost an aha moment. Different problems take different styles to solve, but I see a lot of people on here have the same experience that quality takes time, if you get it on the first time or the third depends on if your environment can tolerate the intermediate steps.
