I was not born blind, I became blind at the age of 12. So I have seen the world and I know what things look like. When I sing about love and pain, joy and sadness, I know what I'm singing about.

Innovation is not about doing something completely new, but about doing it better than anyone else.
The only way to do great work is to love what you do.
