As someone with a lot of anxiety issues, I'm always looking for books that will remind me to be more grounded. Don't Worry offers enough reminders and insight to remember how to treat thoughts and make small changes in dealing with worry, overthinking, etc. I enjoyed the relative simplistic nature of explaining Buddhist terms and Japanese references that monks study and use. In some ways, the book 'does the trick' to help reset my mindset. However, I was somewhat confused how much the book geared towards those in the corporate world, even though that's not really addressed as a theme in the forward. When it doesn't focus on businesspeople, the author felt a bit lost on who they were addressing as readers. The chapters are simplistic, on the one hand, which makes it easy to read and not get caught up in methods and tricks of calming down the mind or one's lifestyle. But, on the other hand, it doesn't feel all that inclusive or personalized. Having read similar books, this is good for those who may be having issues at work or looking for something simple to get started on being more zen.
