Self-confidence can be likened to a muscle that requires consistent exercise to grow and strengthen. The more you engage with it and challenge yourself, the more your confidence will develop. Just as neglecting a muscle can lead to atrophy, failing to nurture your self-confidence can result in a decline in your self-assuredness.
To enhance your self-confidence, you should actively seek opportunities to stretch your abilities and push your limits. By continually working on it, you can cultivate a more positive presence and impact in your life, as emphasized in Susan C. Young's book, "The Art of Being." Building confidence is an ongoing process that requires intention and effort.
