IMHO to really change your whole life perspective, you must experience a traumatic event, not reading a book. Anyway I would say that a book can trigger a change of perspective on a particular aspect of your life: '4-hour workweek' - Tim Ferriss (on lifestyle) 'Get Things Done' - David Allen (on organization and productivity) 'The Way of the Superior Man' - David Deida (on relationships) 'The prince' - Machiavelli' (on business and strategy) 'The little prince' - Antoine de Saint-Exupéry (on meaning of life) 'The Feynman Lectures on Physics' - Richard Feynman' (to make you remember that you are just average) A lot of other books had broaden my perspective of life even if they weren't enough to trigger a change. That list would be immense.
