Whistle While You Work speaks to what I hear daily from friends and colleagues, i.e., work without passion drains energy from life and nibbles away at the soul. This book takes a straightforward approach to how you can be personally responsible for discovering what work will suit you so well that work/energy/passion meld into one. Leider and Shapiro make the ultimate dream of "good work" seem possible, attainable and sustainable. The calling card exercise works so don't pass it up!
