The thing about singing is that if you're having fun while doing it then people will have fun watching you do it. Like in karaoke if you're like "I don't think I can do it" and then you sing a song and you look terrified people will say, "Poor guy or poor girl, get offstage. You're killing us." But if you get onstage and you don't sing that well but you give it your all, people will be like, "Yeah, I'll chug beer to this!".
