a girl wants to know first of all why she should be interested in you, then second of all why you being the interesting, cool guy that you came off across as would be interested in her. Like I said, like her for her. That's as personal as it gets man. Not the fake front girls put off, but the real girl inside. The one that likes puppy dogs and ice cream cones. Find out a reason to be interested in her that's unique. A useful tip for doing this is relating on an emotional level. Emotions are always personal. An entire pickup in my opinion is about creating emotional spikes and valleys in the girls mind. An example of this from a girl I was talking to earlier:
Me: yeah, I just got back from the dance a thon thing, and realized that I can't dance worth crap compared to some of them. Can you dance?
Her: lol, oh that was tonight. haha at least you had fun dancing. and yea i love to dance, been doing since i was 4. lol. (right here is the hook to personal because im interested in girls that can dance)
Me: lol yeah? you lucky then. You get to teach me how to be badass at dancing. What is it that you like about dancing? (right here is me getting her to describe something that's obviously important to her if shes been doin since she was 4)
Her: yup lol. sure i'll teach you how to be a badass dancer. idk it's just that when you dance your whole mind is cleared and nothing else matters. and it's just fun. (in bold are all the values she gave me for me to elicit)
Me: haha that sounds like an amazing feeling to have. I used to run alot.. kinda out of shape now tho lol, but when I did run it was like this crazy peace just set over you. (there I related her values to my life in an emotional way) Damn you make me really want to learn to dance or run now lol. I really want to learn to get better at dancing. What's your number? I will call you make sure your aren't a crazy person :p, and we will set it up.
Her: lol, then you should get up and dance lol. well i'm going to learn how to ballroom dance soon, you should come take it with me, and i'll teach you other things that you want to learn. lol.
That's not the most amazing example it was just the easiest to copy and paste :p, but I do think this will help you understand.
Nothing superficial. All personal.
Then look for opportunities to escalate.
I agree, emotions are personal. Seeing her for her is personal, and after you show this genuine and deserved interest to her, escalate.
