A lot of guys spend a lot of time thinking about the perfect thing to say to a girl or "good" topics of conversation for a date. Though well intentioned, these thoughts and deliberations don't really provide an answer to the actual problem they're trying to solve: "what can I do to ensure that neither of us are bored in the conversation?"

You don't need to come up with a perfect line or the ideal intellectual conversation. Women will talk about literally anything, all you have to do is get them started. Observe something around you, they'll chime in, and then you listen. Ask a question about something they said that you though was interesting, and they'll keep talking. Women talk. It's what they've been doing for decades while the boys were playing in the mud. It doesn't matter what you talk about, what matters is how the conversation makes her feel. You can talk about literally anything - spend your time thinking about how you can use your conversational skills to engage her emotions rather than worrying about coming up with the perfect thing to say.
