I was really excited to try this out based on the hype, and honestly, it’s not bad. There are some genuinely useful techniques and exercises presented, and I have found myself using a couple of them regularly. It's helped me to think about things differently in a few specific situations. However, the claim that it’s life-changing is a bit of a stretch. It’s a helpful tool, a good resource even, but it's not some magical solution to all of life's problems. I'd say it's more of a solid self-help guide than a revolutionary breakthrough. If you're looking for practical advice and are willing to put in the effort, it's worth checking out. But don't expect miracles.
