Seth Godin's book Linchpin is a great look the value individuals provide organizations. My first thought was once you are indispensable the next step was out the door. This does not exist where ownership sees the value provided by individuals and these HEROs provide are the forward motion.
The Desire Map: A Guide to Creating Goals with Soul by Danielle LaPorte: Interesting view on goals. LaPorte argues that we're not chasing goals, but the feelings we get when we achieve goals, which is why we're unhappy yet accomplished. She advocates concentrating on the feelings and then moving back to create goals to achieve those feelings. I think it's a good approach! 2nd half is a workbook, so don't get the kindle version :)
