The four stages of the Drupal developer life cycle, by Ben Clark

The rest of this post has a different, decidedly-non-preachy voice, but this was my favorite part:

If you're a PHP genius, the world deserves to know; if you're barely competent, the world deserves to know that, too. If you won't stand by your work, then we don't want you in our community. Stop believing that you're the only one who will want that feature you're developing. Stop yourself from thinking that your implementation choices are without flaw.

From The four stages of the Drupal developer life cycle. I worked with Ben for a couple years at Jackson River and he's a hell of a guy.
