We’ve all been led to believe self-confidence is the answer to everything. You know the feeling -- if only I was more self-confident I would have asked for that raise. If only I was a little more self-assured, I would have asked that guy out, rocked that bikini or gone on that trip by myself. It turns out self-confidence is NOT the “be all end all” we thought it was. In fact, research shows it's the cause of a lot of problems. Do I hear a hallelujah?
