Seth Godin's Tribes is a treasure store house (I guess that's what a trove is).
Full of good stuff.
As I read the mini chapter called Switching Tribes, his bit on what a seeker is really resonated with me.
His definition of a seeker:
People who desire the feeling they get when they're part of a growing, vibrant tribe, but who are still looking for that feeling.I'm a seeker.
