Cultivate the art of listening
Listening, real listening, is a lost art. People are so busy wanting to talk about themselves, or checking their phone, that they have a tendency not to really listen.
If you show that you care what other people have to say, you'll show that you're a good bet as a partner.
When someone is talking to you, make sure that you give them your full attention. Make eye contact, avoid checking your phone.
If you don't feel comfortable making eye contact, try to look over one of their shoulders, or at their forehead, because it will look like you're making eye contact, without actually having to do that.
Don't make assumptions and don't get quick Conclusion, you need to be relaxed and comfortable and calmly observe.
Listen to all people, even girls you don’t find attractive. This shows that you respect people and that you think all people are important and you're not just listening to someone because you want to get into her pants.
Unless she's only looking for a one-night stand, a girl doesn't want to feel like you're only paying attention to her because you want to have sex with her.
