One word: care. That’s really the topic of this book.

The @author field of a Javadoc tells us who we are. We are authors. And one thing about authors is that they have readers. Indeed, authors are responsible for communicating well with their readers.

the ratio of time spent reading vs. writing is well over 10:1. We are constantly reading old code as part of the effort to write new code.

Because this ratio is so high, we want the reading of code to be easy, even if it makes the writing harder. Of course there’s no way to write code without reading it, so making it easy to read actually makes it easier to write.
