Flip it is one of the more appealing productivity / personal outlook books I've read. Encouraging his readers to challenge their way of thinking, Heppell tackles a range of areas in which we can improve our experience of life through slight shifts in our attitude. Essentially it's a guide to positive thinking. There are summaries, tips and exercises - personally I would have liked more of the tips and less of the 'fill out this worksheet', but that's just my own style of learning and I'm sure others will find the more interactive elements invaluable. Sensible, playful and practical, Heppell's approach encourages us to think of ways to solve problems and always to look on the bright side. I've filtered out a few valuable tips and look forward to putting them into practice. ( )
