This is one of the best books I've read in a long time. I am a big fan of wisdom/self help/mental and emotional health books and this one has it all.
It combines some ancient wisdom coupled with Jay's personal experiences and added to it with a dash of neuroscience to explain how we can all change the habits of thought that we fall into and it also gives practical advice and tools that you can use to implement into your life.
I sense this will be a book talked about for decades.
