I came across this by accident but since I've recently started Dialectal Behaviour Therapy, I've been curious about different therapeutic approaches. I have a copy of The Happiness Trap
waiting to be read, so I had a basic knowledge of ACT before reading this essay.
You've explained Acceptance and Commitment Therapy in a way that's easy to understand but not so simple that the reader feels like a first grader. I'm sure other readers appreciate this as much as I. The exercises you have suggested seem to be straightforward and easy to put into practice by those willing to give ACT a try. I enjoyed reading this and look forward to seeing what other enlightening goodies you have in your portfolio.
