The right to be irresponsible and stupid is something I hold very dear. And luckily it is something I do well.

The idea that there is one kind of African is of course ridiculous. Sometimes African entrepreneurs want to kill you because you are saying public health is the priority, not roads. Of course they are right to press for that issue, but so are we right, I believe, to argue for example that millions of children could and should be vaccinated.

U2 was involved in Live Aid, and I ended up going to Ethiopia and working there for some time with my wife, Ali.

I'm never nervous when I go to meet heads of state. I feel they should be nervous, because they are the ones who'll be held accountable for the lives their decisions will impact the most.

In my view, the only thing worse than a rock star is a rock star with a conscience.

It's still very difficult for me to rely. Your weakness, the blessing of your weakness is it forces you into friendships. The things that you lack, you look for in others.
