Today I said, I can have the rule off today, since I was already checking FB when I woke up. And it made a giant difference in my productivity. I was commenting on threads left and right. I got sucked into an argument.
It's too much. It's a waste of life.
So back to the 9:30 am rule for most days. Ideally I can push it off to noon one day (but that seems so far away).
