Just finished Raeleen d'Agostino Mautner's book. She is something of a cultural psychologist. This is more of a self-help style book than a manual on how to live superficially like Italians (throw on a scarf and heels and sip a glass of wine on your balcony, etc.).
Much of it is common sense, but it is a good reminder of why the Italians seem to be living simpler, more relaxed lives. If your life is totally out of whack, this is a great book. If you already lead a balanced life and have your priorities in order, you may not need this book.
She definitely makes a lot of generalizations, but you'd have to in order to summarize the lifestyle of an entire country. Worth a read when you feel like you are on the hamster wheel, buy it used.
