Well now you are just making me blush! I have never thought of the dance aspect in relation to self portraits, but you might be onto something. I've never been a professional dancer but when I first started taking lessons when I was 11, we were thought to look at ourselves in the mirror the whole time. I still dance at home in front of the mirror, to add to my narcissism.
What comes to the daylight shots I think you speak of, is that I hate taking pictures in the dull even daylight, but one doesn't always have the luxury to just shoot at golden hour. So it's not about exposure, but about the actual conditions. One can't make up shadows and highlights where there isn't any contracts to be found. Of course I always have the choice not to shoot, but for example, when travelling, I'm not gonna miss out on interesting things and people to shoot, just because there isn't the best possible light.
You are definitely right about the focus when shooting in a crowd, I really do not like it when there are other people around. I wouldn't say I'm not confident, but there is a level of limiting myself because I just can't all up in other peoples business with my camera, unless I can do it undetected.
