Think less, be more
Clearly you are interested in how to meet and maintain a connection with other people. I'm sure plenty of other people are interested in that to. But that is not the point. You won't know how a conversation will go until you begin it.
Pay attention to yourself, the world around you and just happily be yourself.
There are questions and answers to ask and not to ask, you know some and don't know others. It is doesn't matter which you know and don't know. Fear will stop you from acting appropriately if you don't see it appear.
