I agree.  And while you're there, check out the other Extreme Programming
principles.  To me, the thing that makes this principle "work" is its
combination with the other principles (most directly "Refactor
Mercilessly").

Also, remember that "simplest thing" doesn't mean "the first thing that
comes to mind".  It can take some serious contemplation to come up with the
simplest thing.  Einstein's advice is also useful here: "make things as
simple as possible, but no simpler".
