Woah woah woah OP, how do you see this as a victory? Let's break this down.
- First you took way too long to make your approach, if you were in a club or a bar or a party that girl would have been gone by the time you walked over. It's ok that you were nervous, but you should at least used that time to come up with a game plan instead of walking in blind. Also, a girl giving you her name is not an IOI. Touching your leg, giving you her number, laughing at your jokes, those are IOIs. The way you write it looks like she was just breaking a very awkward situation.
- Second, you should have teased her when she asked you if you had read the Game. "No I never heard of it, what is it?" "This book for players..etc" "Oh really, so you think that just by sitting next to you I'm trying to play you? Wow, someone's cocky." <--- like that. Asking someone's opinion on something is no one's specific opener -_- .
- Third, and most important,
you talked to her the whole ride and didn't try to number close? EVEN AFTER SHE WROTE A LIST OF BOOKS ON A PIECE OF PAPER FOR YOU. Seriously man, how is not shooing you away after that botched approach not a huge IOI to you, but giving out her name is?

In boxing terms, you created an opening and you didn't take it. You asked why press for more, why not press for more? Just learning to approach is not what you got into this game for, so don't let yourself off the hook just because you took a baby step.
"Hey, can you add your number to the list too? You know, incase I need more coaching/advice." <--- Something like that.
I'm a musician, so I can tell you, this game is a lot like performing…just for an audience of one. Not to bust your balls, but you have got to be more critical. If you aren't going to have a coach, or a wingman, then it's up to you to be your own teacher. The best mentors don't let their students by with sub-par work.
