Well, I skateboarded for 17 years, and I've always been competitive and motivated. I have confidence, I just don't talk much; furthermore Im always questioning others behavior (being skeptical in nature), in other words I almost never entirely believe anyone. So I guess I have confidence in what I do and say, just not so much in what other people will understand or accept, and I accept that. Also, developing and expertise in any area, I believe will boost confidence. For me, expertise is modular, which is why I,m constantly teaching myself. Be passionately curious, don't let what others think effect your interests. Here's a motivational pic I like, it has a nice poignant message-
