And in conjunction to that, this article "Someone is Coming to Eat You" (http://randsinrepose.com/archives/someone-is-coming-to-eat-y...)
It is a great little book, which deals with how we handle change in our lives (work and other) and how we sometimes fail to see, when it is time to move on.
My favorite one-sentence takeaway from the book is the question: "What would you do, if you were not afraid?" - which has helped me make hard decisions many times over the years.
