People look around you, the signs are everywhere. You've left it for somebody other than you to be the one who to care.

More than a career, I feel that I've got a function. I see things in a much more holistic way. Some people bake the bread, and some people write the songs.

Self-discovery in songwriting, bringing something forth that's instructive to yourself - some of the best songs that you will ever write are the ones where you didn't have to think about any of that stuff, but nonetheless that's what's happening in the song.

How long will it be 'till we've turned To the tasks and the skills That we'll have to have learned If we're going to find our place in the future And have something to offer Where this planet's concerned?

We may lose and we may win, but we will never be here again.
