Strongly agree! If you write something cool and you're thinking "oh yeah! I am such a Ninja!" then step back and decide whether it needs commenting to explain what it does. If it does need commenting, consider whether you could rewrite it in such a way that comments are unnecessary. Assume your colleagues and future code maintainers are trainee ninjas at best.
