There are a few ingredients to lowering social anxiety. First, you need to identify from where it came. It's not inborn. If you can't remember then you have to let it go, but know this, whatever the cause, a child inferred s/he was inadequate. It isn't true. None of us are born inadequate, but when we think we are we can create such self-consciousness that it becomes self-fulfilling. You have to have that talk with yourself, that there is nothing wrong with you that you can't fix. Second, you need to get out of yourself. Perhaps, the greatest thing about life is that we get to live it. We get to witness and participate. To do that, we need to get curious. It is amazing out there, and being self-conscious will cause us to waste the miracle. Get curious about others. Get interested. The most worthwhile people are the ones who are curious and interested. Others appreciate it. Third, people of merit are interested in authentic people, as well as highly polished people. Some of us get a late start, and the best we can do is to just be ourselves. That is good enough, if you don't make yourself a burden. You can be humble. You can be a silent watcher who rarely speaks, one who sees, but you must be interested. That makes you appealing to others, someone people would like to get to know. You are interesting, as long as you share your real self without expectation.
