Building self confidence is important, but it can be tough. I really struggled for a long time with it. You know what really helped me? Faking it. Seriously. I just started acting like I was totally confident about everything and anything. Inside I wasn't, but I wasn't showing anyone that. Eventually I started becoming more confident on the inside. I even had one person tell me that I'm intimidating because I'm so confident. It was more than faking it, of course, but it helped me out. Maybe it will work for you, too.
