I relate to Sakura more.
Sakura because she's compassionate, intelligent and solicitous, though on the other hand she could be brash and temperamental, just like me. I've also got the habit of punching people who annoy me (but not strong enough to hurt, of course!). But I can pack a punch. I am a selfless person, always worrying about the people around me; usually my parents. Sakura demonstrates selflessness when she and Chiyo encountered Sasori. Instead of injecting the last antidote vial into her poisoned self, she insisted for Chiyo to take it. She even when as far as taking a stab to a vital area for the old lady. Another comparison would be that despite my soft spot for my parents, I do find them annoying at times. In the sixth Shippuden movie, Sakura complains about her parents. I vaguely remember dieting in fourth grade. The reason maybe was to lose some pounds for my crush. I was pretty chubby, and I was self-conscious about it.
But, notwithstanding our many similarities in personality and appearance (I've got short hair too!), we have our differences as well. One of them mainly being that I don't wear my heart on my sleeve. I can be emotional, yes, but that doesn't mean I let people see it. And when I like a boy, I don't show it. I don't make it obvious and I don't chase after them. That was one of the few reasons I hated Sakura in the beginning, actually.
Anyway, that's it. I might add on to this in the future if I can think of anything else to add. Anyway, Sakura is one of my favorite female characters in Naruto.
