The NMMNG book is quite an illuminating read isn't it?
Something else that has helped me tremendously is the practice of mindfulness, something you hear of but usually ignore. It is a way of fully being with what is going on in life without getting caught up in liking/disliking and being judgmental.
Have a google for it, there are a few good books around by John Kabot-Zin that give an easy intro to it. He runs a Mindfulness Based Stress Reduction clinic that helps people to deal with major stresses, the people he has helped include chronic pain sufferers, people with terminal illnesses, police officers and etc.
