Lack of self-confidence is, more often than not, simple laziness. We feel confused and uncertain because we do not know. But instead of making the effort to investigate, we procrastinate and worry. We tell ourselves we can't instead of learning how we can. If we used the mental energy we expend in worry and fear to get out and find out about what we do not know, we would see our self-confidence grow. Lack of self-confidence is not overcome by faith, but by action. It is a lack, not of certainty, but of effort. Too often we are certain that we can't before we give ourselves a fair chance.
