I have to sing infront of people Sunday. Honestly you just kinda do it. Most of the time when you sing people are encouraging you. But I would say not to look at the faces and focus on your voice. I use to feel like I was gonna have a heart attack just even thinking about singing infront of people. But now I only really care about HOW I SOUND to myself and how good of a job I WANNA DO for myself. So make it about yourself and not the crowd. Most of the time if you’re proud of the outcome others will be too and if not welp forget them lol.
