Twilight Sparkle MLP Theory

This is a really short and simple theory, but surprisingly I don't think anyone has picked up on it. I think Twilight Sparkle's destiny was always inscribed in her name. She united the princesses of day and night, and her name is TWILIGHT. Halfway between day and night. So she was always destined to do what she did! Really obvious right? And all the other ponies have their jobs or personalities in their names, FlutterSHY, APPLEjack, Pinkie PIE, so why not Twilight too? It just totally makes sense!
