It's been a busy day, dominated by an unpleasantly aching head (my own) for several hours. Funnily enough, the headache pretty much disappeared after some fairly hectic rehearsing in the early evening. Not quite what I expected, but a very welcome outcome.
I'm hoping to sustain a reasonable level of energy for the next couple of weeks particularly. There are busy days ahead, demanding days, and past experience suggests due recognition of the demands, if not actively embracing them, is the best way forward.
(Having no choice in the matter helps, of course.)
