Arch-enemies give you focus. They show you what you're not trying to do (if you're trying to be your archenemy find something new to do where you can contribute); they give you a public face you can battle against; they give you a reason to want to improve yourself. If you are the enemy people want to fight, spare no prisoners. The Evil Overlord list (http://www.eviloverlord.com/lists/overlord.html http://www.eviloverlord.com/lists/overlord.html) will help you immensely.
