Confidence is not really a problem of mine. I can walk up to a girl and say hey or whatever easily. Asking them out has never been a big deal to me. My problem is, I don't know what to talk about!

This isn't just for chicks actually, I find myself the same way when trying to socialize. I'm usually fine in a big group and can usually make good jokes carry on a good conversation, but starting those conversation is a big problem for me. Wtf do I talk about?

In high school btw. I would post in the high school reddit but this one has many more members. I've read the FAQ but it doesn't really apply. I don't need 'pick up lines', I need to create interesting convos with chicks.
