Let's take something like antidepressant medications. There's decent science saying it has an effect, but it's shockingly small after you control for penetration of the blind, people knowing that they're getting the active pills versus sugar pills, if you use an active control. It's probably only a few points. But it's a multi, multibillion-dollar industry. And by the way, has huge side effects. 40 percent of the people taking them have significant sexual side effects. And that's just one. A single antidepressant medication can be worth a billion dollars to a company.

Go inside the sweetness of life, catch the places where you genuinely were moved by or connected with life, and you'll find in there kind of a light that can direct you when the cacophony gets very noisy and you get confused and lost, that can direct you towards what you care about.

ACT psychology is a psychology of the normal. A lot of the psychologies that are out there are built on the psychology of the abnormal. We have all these syndromal boxes that we can put people in and so forth. The actual evidence on syndromes is not very good. There's no specific biological marker for any of the things that you see talked about in the media. Even things like schizophrenia - there's no specific and sensitive biological markers for these things. There may be some abnormal processes involved, but vastly more of human suffering comes from normal processes that run away from us.

One dangerous definition of happiness is to think of happiness as kind of a warm, joyful feeling in your heart that you have to pursue and grab and hold onto for fear that it'll go away. A better way to think about happiness that actually is something that I think you can reach towards is, it's living in accord with your values and in a way that is more open and accepting of your history as it echoes into the present, that's more self-affirming, self-validating and values-based. The Greeks had a word for it; they called it eudaimonia. And it is something that will empower human lives.

There are times when you felt especially important to another person, or cared about or loved or accepted. Well, loving relationships aren't something you can have like a precious little jewel you put in a box and then put on your shelf. It's something you walk towards. And there's always difficulties; there's always pain in relationships. But you can keep walking towards that beacon in the distance. That process, that journey, is called life. And if you're moving towards the things that you value, life is more vital, flowing; it's more empowering.

But this cheap-thrill version, this sort of ease definition, the feel-good definition of happiness is an empty promise. Unless we get wiser as to how to carry the difficulties of life in a way that's self-compassionate and empowering, we can create this kind of world in which we'd rather sort of plug into the matrix with whatever pills or escapist tendencies we can think of instead of walking through a process of living that's going to include loss. It's going to include limitations on function. We need to learn and teach our children how to do that.

In Scandinavia probably the most worker-supportive part of the planet, they have the highest rate of chronic pain and worker-related disability. So any kind of pain and difficulty is so much unwelcome that if you say that you're in pain, we're going to even pay you full salary to quit work because you're burned out, inside that what you're going to create is gigantic amounts of chronic pain syndrome. Scandinavians spend 15 percent of their gross national product on disability. 50 percent of the public health nurses are on disability. And that's where we're headed in the U.S. too.
