For me, I've always thought the two most important things are rewarding work and strong realtionships.
On the whole, I've achieved rewarding work (which for me included a short period as SAHM) always looking to develop and progress, but am finding as I approach the possibility of early retirement I care less and less.
So, I guess the purpose of my post is to discuss how I can stay "engaged" when I don't feel there's anywhere further to go and may leave within a year or two.
Also, if I do take the early retirement option, where do I get the "rewarding work" part of a happy life?
What else do you find key to a happy life?
