A singer for me is more like someone who is standing alone with a microphone like Scott Walker rather than someone who is bashing a plank and is spitting all over a microphone.
To have ego means to believe in your own strength. And to also be open to other people's views. It is to be open not closed. So yes my ego is big but it's also very small in some areas. My ego is responsible for my doing what I do - bad or good.
