I never get how people decide like, which one they're most like?

Is it a case of 'omg x is such a cool princess so I aaaaam like her' - because really, I have qualities with most of them. I just say Jane because British - Tick Clumsy - Tick Likes Animals - Tick.

I don't know, it always baffles me when we connect with certain characters. Like, I like Arya from GoT and I will probs change my set to her again for GoT month (or w.e) but like, what do I actuaaaallly have in common with her. Idk.
