I don't read too much non-fiction, but this one really drew my interest as I'm interested in attention and focus and improving both. Dr. Jha makes a great case for mindfulness-based attention training, accessibly describing her own research as well as other relevant neuroscience research. Her argument in favor of mindfulness training as a way to strengthen attention is effective because she has tried this approach with people with some of the highest-stress careers that require incredibly strong attention, like deployed military members, first responders, fire-fighters and more. The only thing that wasn't a home run for me about this book is that I personally find mindfulness exercises really challenging unless they are guided, and typically in a guided audio format. I had a hard time engaging in the practices described because I kept having to go back to look at the text to see how to do it. That's more of a personal preference though, and isn't really about the book itself.
