I work as a stress management trainer for humanitarian relief and development workers around the world, so I've read a lot of self-help books in my time. This is one of the best I've read. Beautifully structured, it's finely balanced between research, anecdotes and application. It kept my attention throughout, and most pages now have highlighter on them. It's well worth the time to read and will challenge you gently, but firmly, to assess your priorities and how you are living your life.
