It doesn't worry me a bit, because I feel that he'd never completely forget about his music. But even if he did, the lives he fights to save are infinitely more valuable than all the U2 albums ever purchased. Honestly, I think he wishes he could be more focused on U2, but somehow people don't seem to care or realize what's going on in Africa and if he doesn't speak up, no one will. I think a lot of people take for granted the hard decisions he has to make, like balancing time between his family, his music, and his humanitarian work. I once read somewhere that if he could have one thing, it would be more time. Personally, I've only ever met one person from Africa suffering from AIDS, and that one experience was enough to weigh on my heart still every day. I can't imagine what it's like for Bono having been around so many people like that, trying so hard to make even the slightest difference, and then dealing with accusations of being egotistical, preachy, and selfishly motivated. That makes me sick. To me he often looks frusterated and genuinely concerned with the lack of reaction to the AIDS pandemic and poverty in Africa. Maybe U2 is becoming a side job for him. If that's what it takes for him to get his message across, then I only respect him more for being willing to give some of that part of his life up to help people who can't help themselves. It's people like Bono who make me believe this world is worth living in.
