How to not be shy?

The first place to start is to stop caring about what people think of you. Once you realize that you are your own person, it becomes alittle easier to open up. It'll definetly take some time, but you will be able to conquer shyness. For me, it took dating my wife to crack open my shell. Now I never shutup. I still have a shy tendency, but it's alittle easier to talk to new people now that I don't care as much about what they think of me. Best of luck with this!
