"The world doesn't have to be the shape that it is. You can kick it, cajole it, you can help give it a better shape. When you're younger there is a great clarity. I miss it. But as you get older, you realize one of the biggest obstacles you will come across in your life is yourself. That started in our music with (1991 album) 'Achtung Baby,' that's when we got into the hypocrisy of the human heart." - Bono, 2015
