I'm still ill but today I've shifted from the Exhausted in Bed stage to the Quite Tired But Wanting to Be Productive one.
I'll see how long that lasts.
Anyway, the productive part is the challenge. I'm not in the best voice to call clients, serious e-mail is approached with caution, and it doesn't make sense to go to the office and infect others.
But since the mind is wandering anyway, why not jump on its back and jot down various ideas for new products, twists on established ones, and matters to discuss with various people? The points may be amusing later - How could I have thought that would work? - and yet thinking with the fences down may produce some breakthroughs or guides leading to them.
