Confidence has nothing to do with arrogance.
Confidence is being aware of your ability while taking action. Behavior drives confidence.
Arrogance is about a comparison, it is feeling you are better than someone. Confidence is about knowing and acting in a way that aligns with your potential.
Comfort is anti-confidence. When we are comfortable we are not growing, we are not progressing. Confidence comes from our actions and the results we produce.
Real confidence is about freedom. The freedom to live and grow the way you were meant to.
