It was a quick read, and I should say I’m a bit disappointed. If you want to save time and money – go to the book’s web page and you’ll get all main ideas that are described in the full version.
Yes, the world is changing very fast. You don’t want to become a Detroit of the modern age. You should not expect a life-time employment in one company. Go learn new stuff, go meet people to find interesting opportunities. I was expecting a more insightful book with less direct LinkedIn service promotion, but in the end got a help-yourself, very Silicon Valley-centric guide on building a network using LinkedIn.
Unfortunately I cannot recommend this book, unless it’s news for you that you need to invest in continuous self-education and network building to succeed.
