Faith comes from fear
Where does self-confidence come from? Confidence comes from fear. We all have fears, for example, when talking to parents, facing a boss at work, or competing in a game. To overcome fear, you must muster the courage to face it. Courage fosters self-confidence to face something.
Confidence can be said to be an indication of fear. This is different from someone who is overly confident. Those who are overconfident are not afraid of anything, and this is not a good thing.
Face every fear that arises within you to cultivate self-confidence. It may seem overwhelming at first, but the more courageous you are to face your fears, the easier it will be for you to increase your self-confidence.
