As a songwriter, if you can touch people and make them feel a little less alone in the world, then you've done your job.

I even got letters form kids in hospitals saying the music is what keeps them going, and that really touched my heart.

I think if you're a good songwriter, that's what you are first - not a star or celebrity.

I believe a lot of disease comes from anxiety, loneliness.

The pursuit of happiness is in our Constitution. We're all entitled to have the best we can.

This is the price you pay for having a great father. You get the wonder, the joy, the tender moments - and you get the tears at the end, too.

My philosophy is very much to encourage my children to forge their own success and happiness, even though that will undoubtedly involve much more modest levels of wealth creation.

Fatherhood is a joy. I feel very lucky to have a family. It gives you a perspective on things.
