Sorry, book, but you're not the one for me. There may well be good strategies and insights here, but the assumption throughout is that the reader has "made it" in the corporate world. Cannot relate: all I've made today is multiple mugs of tea.
I think the book I'm really looking for is called "The Bumper Book of Burn-Out for the Chronically Self-Disappointed" (Please, God, can someone write it soon: don't make me have to do it!)
