We often view celebrities as self-serving ego maniacs who only care about their money and their fame. In some cases, I would say this is true. There is however, a great potential for those celebrities to impact the world through their audience. They may not realize it, bu twhen they start to care about issues of Global importance, they influence ordinarty people to attempt changes in their daily lives that can help others. This is something that I see in the life of U2 singer Bono. I admire him very much, and if I were a musician, I would do the types of things he does to influence the world around me.
