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?
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.
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.
