There are hundreds of "how to manage" books about - they rarely say anything ground-breakingly new. However, the good ones will paint old messages in a new way, and allow breakthroughs in understanding, and perhaps a shift in perspective. "Everything I need to know..." does just that. It reframes what can seem like an incredibly complex and frustrating discipline to something more manageable and even logical. It does so with great humour - putting yourself in Buzz Lightyear's shoes for a moment as a manager can transform a problem immeasureably!
Highly recommended - a "Who moved my cheese" for the Naughties.
