You've got to have pain. And more importantly, you can't kid yourself about how in touch with your emotions you are. I'm not going to mention exactly which recent documentary I saw on a "multicultural contemporary South African band" that made me think of this.
You can't sell your political ideologies (as they are probably less than informed) and you can't keep thinking about what your audience wants to hear (they are hardly a yardstick). You have to sell your feelings and your honesty - sell your pain. Even if all you have is happy pain.
