Find a specific field your language would be useful to. I tend to think that having it be a scripting language (eg. one that's ment to be used as, for example, creating quests / scripting events. Like old Gothic [I and II] used to have) justifies creating it (and potentially could be useful, since the main contenders as far as I am aware are AngelScript, LUA and Squirrel - so there's not a plethora of choices to choose from). Though you could find any other field where the language could be used for. Perhaps processing data, or maybe analyzing human language. Whatever you can come up with. Then it kind of makes sense :D
