That term's definitely got a negative aura to it because people think a diva is somebody with an attitude who demands things all the time. Of course there is that type of diva but my idea of a diva has always been a singer - whether male or female - who gets on that stage and captivates you with their presence and their voice.
I think I've learned that if you want to be successful you have to tell your story honestly and from your heart - and I think a healthy sense of humor doesn't hurt either.
