Self confidence

I have always always lacked self confidence. It was a factor in constantly feeling like I'm good enough and being shy. Within the past 3 or 4 years, I have finally broken out and became more sociable which I believe has helped me gain some more confidence. I still struggle with it, but I find it helps to not show it. If I can make others think that I am confident then I find it easier to help myself feel more confident.
