Good for you, Pete! I share your urge to be doing something that feels productive to me, and sitting just to be "relaxing" is an impossibility. My wife once told me that I was "radiating waves of anxiety and boredom" instead of relaxing.

She constantly reminds me of the story of the wood cutter who made himself stop working for ten minutes every hour to sharpen his saw. Her gentle reminders were, "M'dear, you need to sharpen your saw," and that was a flag that I was "radiating" again.
