Take it real easy for a while. I think the idea of retiring is a big deal, in the back of many people's minds. You think you just go right on and pick up your new agenda, but it is a bigger emotional step than one may think. So give yourself room and time to adjust, get plenty of rest, and tend to your health until you get your footing. Once you see how engaged you are with your new life, off you'll go again. But allow yourself to make the change.
