A clear mind is what makes men succeed with women. If you're not thinking about if she likes you or what should you say you're gonna notice that you'll get good results. Here's a few key things to keep in mind.
1. Ask questions to get her talking.
2. Talk to her from a dominant standpoint...you control the encounter.
3. A well timed joke shows that you're witty, but it's not the end of the world if your timing is off. Let the opportunity present itself
4. Stories are good but you don't want to be just a story teller. If something cool happens to you then you can share it with her. If not, then something cool will happen and you can share it then.
5. Talk to a lot of hot women so you can get more comfortable talking to them. If you get nervous, that feeling will pass the more you talk to them.
Last but not least, the less you care the more you succeed. Women love when men have an opinion, a point of view and have a backbone...even if you disagree with her. If you disagree with her, don't say you agree with her for brownie points. If she steps outta line don't worry if she likes you or not afterward but check her. If she gets mad...don't worry about it. She'll respect you and that is the primary goal. Once the respect is there then the attraction can come later on.
