Hi, so I have gotten pretty good at introducing myself and the first conversation. This includes talking about "where I am from" and other basic stuff. Ive gotten so good at this that I can pull a girl back home only telling her basic stuff about me. However what my problem is that I dont know what to talk about the next time I see them.

For example, directly in front of you is a girl and she runs up to you and hugs you because you left a good impression from the day you introduced yourself. I have already told her all the basic stuff about me (foreign, sports, etc). She says "Whats up?" What do I talk about?

This is probably my worst problem. Girls see that im a really talkative and interesting guy the first day but the next time im struggling to talk about anything.

Any help or tips would be greatly appreciated. Videos too
