I just finished Crush It! by Gary Vaynerchuk while on a flight from Dallas to Sydney.
I have to say this was a really great book.
It was a very quick read (about an hour), it gave some insightful advice regarding social media, and it stayed true to the Vaynerchuk in your face style.
It emphasized the fact that even though you have to give your business your all, you still have to put your family first.
I would recommend picking up a copy if you have any aspirations of starting your own business.
It applies the rules of social media to the most esoteric businesses and explains how by using these tools you can capitalize on the Internet and social media movement no matter how brick and mortar your business happens to be.
