Where, Oh, Where, Has My Little Dog Gone?

The title is actually a title of a song. I, however, am not speaking of my little dog, but my abundant youthful energy. I seem to have misplaced it. I have looked everywhere, but I simply cannot find it. I wish I could buy some, or acquire some in some other easy manner (way), but it seems it is not to be. As the French say, C'est la vie (such is life).
My energy seems to run (come & go) in cycles. I may have 2 or 3, sometimes 4 or 5, days with a relatively good to (occasionally) excellent energy level, and then 1 or 2 days when everything I do seems to be a struggle, including, but not limited to, getting out of bed, getting dressed, going out my front door, etc., etc...
It is usually best for me if I use these low (sometimes very low) energy days to rest. Sometimes, like today, these are good days to read for pleasure (enjoyment), and try to give King Edgar (for those of you who don't know, King Edgar the Magnificent is a cockatiel, the smallest member of the parrot family of birds, who is also my responsibilty and my master. I am but his humble servant) as much attention as I can. Other days, I don't even have the energy to concentrate enough to read, so I watch a lot of bad t.v., and, you guessed it, give King Edgar all the attention he demands.
Is there a lesson here? I think so. To take advantage of those days when I have the energy, and to allow myself the rest and relaxation I need on those days when I can't find any energy to speak of.
And, of course, to never waste energy unnecessarily, which means, I must do my best to stay out of trouble...
