STARTUP YOU: And while you're studying up, take some time to, say, recruit your very own board of directors. Or at least that's the view of Reid Hoffman, founder of LinkedIn and angel investor par excellence, who contends you should view your entire career as a start up. His book, The Start-Up of You, is just out. And yeah, it hit number one on Amazon.com the day it came out. (Helps to have all those LinkedIn friends!) Smart quote: "The fastest way to change yourself is to hang out with people who are already the way you want to be."
