Aha, being shy, that's an interesting topic. A stranger I met on the local buses in Florida once told me something interesting about shyness. Mind you I tell this not to seem mean. XD Just repeating what I heard and it did help me a bit.
He said that being shy is selfish to a degree. In shyness, and i know, I've been uber shy in my life, especially when I was younger, shy people are so worried about themselves. They worry about how other see them, or what others think about them, etc. It's all about them and your feelings and your thoughts, etc.
We talked a lot more about our own experiences, but that was the main points he made. I think it's a bit harsh to say that being shy is selfish, but if you think about it, it makes sense. It has helped me WANT to be more open. I know people WANT to talk to me and get to know me. A lot of people here are shy too, and WANT to feel involved and welcomed. This is why I try to be open to my watchers about life and just in general, especially with helping them when I can.
