I guess it comes naturally to me.  All you need to do is be bold when trying to start a conversation and find common ground. It helps when you know a little bit about everything and have engaged in different interests through your lifetime. Just like my heart jumps whenever i talk DJing with another DJ or to you,  when you're talking about a favorite movie of yours with someone new.

It's all about finding that common ground, keeping up with the chat even after you guys part and keep on meeting from time to time. That's how you make friends

On the other hand,  you can make lots of acquaintances by simply being cool
