I'm not sayin that this will work for everyone, but it works well for me. First off, when you go out at night, wear a nice suit, watch, and cologne. If you look good, your gonna feel good. Women can sense when a man has confidence and they like it. Second thing is that you need a spot on back story. If I'm rolling with a pack of wolves (my guy friends) I may or may not include them in the story, depending on their ability to lie. Thirdly and this is the most important thing of all... When talking to a "prospect", listen to what she is saying and play off of it. Be sincere and throw in a compliment here and there and your home free.
Also, if you hit it and you want to hit it again in the future, buy her breakfast the next morning. This token amount of cash gives them a false sense of meaning in some weird way.
