There are many forms of confidence. For instance, you are confident in your ability to program and so you program more efficiently than say.. someone like me, who is less confident in their programming abilities. So the question you should be asking yourself is: how did you become so confident at programming? I would be willing to bet that practice is the answer. The same is true for social confidence, you need practice. You need to fail so that you can learn. You need to push boundary's so that you can navigate them better in the future. I would suggest you go join a bowling, golfing or pool league of some kind. Practice interacting with people in an environment where you can be comfortable making a fool of yourself knowing you don't have to come back the next day. I wouldn't suggest attempting to make a fool of yourself, but in the event you do (because you are pushing boundary's) you won't have to worry about it because you don't HAVE to go bowling again next week. So, my advice, practice practice practice.
