This self-published book teaches the ideas of the One Solution NGO, through explication and then personal stories of work with clients. Briefly, the One Thought is that our perception of the world is mediated by thought, and so we have the opportunity to change our perception by being more aware of our own contribution to the process.
Sounds fair. The idea is the basis Buddhism, psychotherapy, and arguably the idea is simply Philosophy -- thinking about thinking.
And it sounds like Gleason and her colleagues and clients have a lot of success with this idea. I have some issues, though. For one, most of the examples are drawn from middle or upper-middle class white lives. A CEO of a company realizes he doesn't have to be such a jerk to run his business. Great.
In the last chapter, Gleason claims that this method has been helpful to combat racism, help refugees, and deal with larger global problems. I would have enjoyed the book more if she went into more detail about those stories. Her example about racism is that babies are not born being racist, and so there's no reason racism exists. I'd be more interested in how a black person in America deals with racism -- is it all in their mind? Does a different mindset help overcome real barriers?
There's something a bit Ayn Randian about this exercise as well. You can free your mind, sure but to what end? If it's all your own perception, does that make you a Nietzschean superman, untethered to the bounds of human morality? Do you become Raskolnikov and kill an old woman to prove you are above petty perception?
In other words, this mindset is a tool, but I don't feel like the tool naturally and necessarily flows to the ends that Gleason is advocating.
Aside from a vaguely cult-ishness about the program, the book is easy to read and I enjoyed thinking through the implications of what she is saying.
