Confidence follows practice, not the other way round
Many people wait to feel confident before they try something new. In practice, confidence grows after small successes. Pick one tiny goal for this week, something you can do comfortably. Notice what went well afterwards, not only what did not. Your body learns from calm, repeated experiences, and so does your mind. Over a few weeks the nervous voice gets quieter.
