Whether or not you get to actually do a 5-hour work day, this book inspired me to change the way I approach work. It is so easy to get into the idea of a 9-5 mandatory drudgery, but since reading this book, I requested a work schedule change to 8:00-4:00, but also just approach work differently. I don't want to leave work having had a bad, unproductive day, so I've made changes not only in when I work, but how I work. Definitely worth the read.
