i've been on stage since i was 15 singing live guitar and vocals no autotune to help me out nervousness doesn't just feel bad when you sing but it will literary break your voice your throat tightens, you lose control... ...and everyone can here it (probably hurting their ears, lol) there's no hiding you either get comfortable being that exposed or you quit over time I got used to it it hindsight, it was the best preparation to talk publicly that I could get because if you managed to sing/perform on stage, just talking seems like such a low lift
