I met this poet named Brendan Kennelly. I have known him for years; he is an unbelievable poet. And he said, "Bono, if you want to get to the place where the writing lives, imagine you're dead." There is no ego, there is no vanity, no worrying about who you will offend. That is great advice. I just didn't want to have to find out outside of a mental excursion. I didn't want to find out the hard way.
