In all of my looking at happiness, one thing I noticed right away is that the opposite of happiness isn't unhappiness or even depression, it's anxiety. It is something that can constantly block our happiness, or our chance to reach that sort of meditative state in our work or our home lives.

I think there are different kinds of happiness. We know when we're happy a lot of the time, but then there are those moments that have more of an afterglow, when the happiness has more depth.

The first person who ever told me that happiness was work was this manic-depressive artist I knew when I was in my 20s. I was like, 'What are you talking about? Happiness just happens. That's even the root of that word. How could it be work?

Artists and writers have to understand and live the truth that what we are doing is nourishing the world.

I've been thinking about disowning some of my genes lately. I have a few healthy, happy, long-living optimists in my family tree - most of them fans of Christian Science founder Mary Baker Eddy, a major champion of positive thinking. But I've got plenty of ancestors who played out more tortured hands.

It is a great paradox and a great injustice that writers write because we fear death and want to leave something indestructible in our wake and, at the same time, are drawn to all the things that kill: whiskey and cigarettes, unprotected sex, and deep-fried burritos.

Nourish the world with your words, yo.
