There's a lot to be said for the KISS principle. As an engineer, I first came upon it when I was reading up about the American Lockheed SR71 reconaissance aircraft.

KISS is an acronym for "Keep It Simple Stupid" and it was displayed as a large sign above the Lockheed factory floor.

You can apply the KISS principle to most things in life and there's much to be said for keeping things simple. Which reminds me of that other well known saying: "If it 'aint broke, then don't fix it".
