Monday, Monday -- what can I say? It was a mediocre day, at best, but nothing terrible.

I once read that Monday was "the 12 percent day" -- people only use 12 percent of their energy (or something like that) for the week on Monday.

So my question is: If I use more than 12 percent on a Monday, do I get to slack off a little bit on Thursday or Friday, just to make up for it?
