It also works for Sunset Shimmer....in fact I think it might work a little more for her...and with Wonderbolt money she'd be able to afford the best schooling possible for Sunny...Which would eventually lead to an over achieving attitude once you mix that with wanting to live up to a Wonderbolt's expectations...which leads to her putting everything she has into magic and becoming Celestia's student!
