I went to a U2 concert last night. It was fantastic. Mind blowing. After all these years, U2 still attracts people of all different ages and backgrounds. It's even more admirable how Bono uses his popularity and songs to try and change the world; to talk about the issues we frequently like to avoid. He brings visibility to the issues happening in Africa and tries to do something about it. Very few people, Bill Gates is another exception, think "bigger" than themselves. At the risk of getting too philosophical, I think it's important for everyone to think about what impact they can make in other people's lives.
