I like this part:
Well, he has an enormous ego, but so do most of the people I like. [laughs] And also a big ego isn't necessarily a bad thing. A big ego means that you have some confidence in your abilities, really, and that you're prepared to take the risk of trying them out. I really don't think he's arrogant. That's a different thing.
I've always been puzzled by that particular criticism of Bono. So he has a big ego - what rock star doesn't? It's not like you hear about him walking around being a total prick to everyone, in fact you always hear the opposite. So who cares if he has a big ego?
And he's often very self-depracating, which goes a long way (at least with me) in balancing out what's perceived as having a big ego.
So that's nice to see the "ego" vs "arrogance" thing mentioned.
