There actually are about six or seven emotions, or so I'm told. But the one state you should really try to avoid is confusion, which isn't actually an emotion but instead a state of mind. Code created by a confused mind shows itself in the randomness of naming, which is not handled by modern, fascist, programming languages like Go. Sure, you may have your names in the proper case and your spaces in the proper place, but you can still name a function PublicThingTwo() if you want to, and this is a sure sign of trouble.
