How to become more social: http://www.SocializeInStyle.com
An interesting and counter-intuitive way for you to become more social is by using the strategy "joining forces against a common enemy". When you're out in public and you find yourself in a scenario where there's something wrong with a public system, you can draw attention to that problem. By showing others that you guys are on the same page, you can begin to start a conversation. At this point, it's your responsibility to turn the social interaction around from a pessimistic state to an optimistic state. This is a good way to be more social.
