It's much easier to be successful than it is to be relevant. The tricks won't keep you relevant. Tricks might keep you popular for a while, but in all honesty, I don't know how U2 will stay relevant. I know we've got a future. I know we can fill stadiums. And yet with every record, I think, 'Is this it? Are we still relevant?'

There's a point where you find yourself tiptoeing as an artist, and then you know that you're in the wrong place.

I felt rich when I was 20 years old and my wife was paying my bills. Just being in a band, I've always felt blessed.

Stop asking God to bless what you're doing. Find out what God's doing. It's already blessed.
