Awesome book. There so much common sense in here it should be illegal.
The most important lesson to gather from this book is that your employees (if they’re knowledge workers, but who isn’t in this day and age?) are an asset, and not just an expense. In the information age you don’t invest in machines and buildings, you invest in attracting and retaining the best people. Putting these people in offices that are cramped and not conductive to knowledge work is like not taking care of your machines or buildings — you’re effectively destroying capital.
