Another tip is to be a bit vulnerable but also dominant. In other words ask people to do you favors. If someone does a favor for you they justify in their mind that they like you, because why would they do something for someone they don't like? Then after that part try to memorize something about people you meet. Could be something about a hobby they do or their family. Then when you see that person again ask them about that thing (and then try to find more things about them for future interactions). Why do you think so many people ask what time it is, or if you have a cigarette, or what the weather is going to be like? They are trying to get you to do a favor for them so that they can connect with you.

Keep in mind that people aren't really taught how to interact and socialize anymore. Don't be offended when people forget your name or don't ask about your life or look distant when you are socializing with them. It's our instinct as humans to think the person doesn't like us and to beat ourselves up about it. In reality it's just that people are very very isolated and spend their lives only seeing interaction online, or through movies and TV. This makes people really bad at socializing. That will change after you have a few interactions with them and they see you as someone who is close to them. Until then you, as an intelligent and social person, have to carry the weight of the blooming friendship.
