Query: Possibly the dumbest business book I've ever read.

You can tell that the authors (1) wrote a strong book proposal that (2) covered the first two weeks of work. The proposal sold, and then they were stuck with trying to come up with ten more weeks of advice. The result is a deeply repetitive, inadvertently condescending book that gives you advice that is both obvious and ridiculous. Don't wear T-shirts to the office. Ask everyone around you what they think of you. Pay attention to trends. Manage your time. And don't forget - don't wear T-shirts to the office! It's well-meaning, but perhaps most useful for recent college grads. It would have been helpful for the authors to target a more specific audience. The authors' attempt to be as general as possible gives the impression that they've never actually worked in an office - only read business books and watched Office Space. If I could figure out how to demand my money back for a Kindle book, I would.
