A workbook, not a theory
This 2005 book is a kind of workbook. Instead of merely explaining acceptance and commitment therapy, the authors propose exercises the reader completes over the course of weeks, with pen and paper, touching on areas like anxiety, sadness, shame, and self-criticism.
The underlying idea is that the human mind, so good at solving external problems, is poorly equipped to solve internal suffering. When we try to eliminate bad feelings through logic, we often make the problem worse, like digging to get out of a hole.
The book grows out of one author's own experience with panic attacks and the research he conducted afterward. That personal journey gives the text a human tone, mixing data with confession.
An everyday example shows how this works. Someone who spends the night turning over a mistake made at work is trying to solve a problem that has no practical solution, since the event is already past. The mind insists, and exhaustion the next day collects the bill.
