Got it and started reading but haven't finished. So far, very good philosophy (although not new - see buddhism and City Dharma) Only gripe is that the writing is a little simplistic.
However, it is a basic concept, that whenever I remember to practise relieves stress and makes day to day (and min to min) living much easier and more enjoyable.
If you were asking is it worth buying, I want to say yes because it is definitely worth reading. However if you can borrow it, that would probably be enough.
