Developing confidence is like watching the sun rise. First it seems very feeble and one wonders whether it will make it. Then it shines and shines. Confidence is not about arrogance or pride. It is a natural unfolding process. It's not a question of needing confidence or not needing it. It's naturally there. In fact, we actually don't have to develop confidence. It's more that we have to acknowledge the confidence that already exists.
