I like to think of it as that; you should have principles, such as trying to write DRY code, but any principle taken too far will end up being a bad thing. Don't be an extremist. Practice a sensible balance in everything you do.

This goes beyond programming as well, I think it goes for most things in life.

In every trade or art you start as an apprentice. That is the time when you learn the basics, the rules, the best-practices. When you have mastered the state of the art, you are a master. You know when to apply which rule and tactic to create masterful artifacts. The next step is to learn when you should break the rules and general wisdom. That is where true wisdom starts.
