So, WW means WATCHFUL waiting.
Explain the WATCHFUL part. Apparently, it means when something new happens and it's urgent, I'll do something.
Each to his own.
Good luck to you.
A few comments about worrying:
You are correct, I worry too much but far from all the time. I worry at test time, often for 10 days or so preceeding it. I admire those who do not worry. I often think that if I had a steady stream of zeroes with a curable situation, I would not worry. But in reality, I probably would worry -- is this the time it comes back?
