Thank you PL. I guess I will get the Bible out of the way now that you are mentioning the Christian angle. The benefits of reading this are probably pretty obvious to most Christians.
Another book I have read, or should I say, listened to (I mostly do audiobooks on my iPod), is...
The Little Book of Letting Go
I admittedly didn't finish this one but what I did read was pretty good. It's all about how to let go of the things that cause us anxiety on a daily basis. It's a real hands on kind of book with a lot of exercises that you do as you read. I read this at the right time in my sitch because it's simple approach to a complex problem really helped me learn to detach and approach my sitch from a different perspective.
