I'm most like Applejack, with Twilight RIGHT behind her.
I was a bit surprised by Applejack, at least with her description. She's my favorite Mane Six and personality wise, I think I am like her. But the description made a big deal about her athleticism, which I have no interest in, and her hard work, and I admit, I'm a lazy bones. Twilight's a pretty accurate second though!! XDD
