It's not a joke. Sometimes you sleep funny, wake up tired and feel cranky all day. No comic timing required.
Do you ever work funny?
Ever have a day when none of the things you need to focus on materialize, when the emotional labor doesn't come naturally?
Most of us have come up with a strategy for days we're working funny–we do the busy work, we reply, react and occasionally respond. We show up at the meetings and we answer our email, and we go home feeling as though we accomplished at least a little something (though we didn't.)
The danger is this: this working funny habit leaks into the days when we're on our game. When you're on a roll, you still find yourself going to meetings, answering email and working through someone else's to-do list. That's a waste.
Don't toss and turn if you don't have to.
