Singing needs inner powers, dancing needs great strenght. Although, when you think about it, being great in something that requires both of those things. And more. Oh, way more. Holding a mic for an hour is a challenge? So it is to dance. And sometimes, being great requires just raw talent. You can't make yourself talented. The talent comes from something around you. You won't even notice it, until someone wakes it up. Sad, that it's not destined for all of us, to have a talent waken up.
