Start of the End

Well we're at the beginning of August which brings us to the end of summer vacation and into back to school mode. So I wonder when do most parents start the back to school routine. I've read the 7 Habits of Productive People and many other self help books. So I have it I pretty down pat.  Our routine starts 21 days out  from the start of school. Earlier bed times and such. So what's yours?  I would love to hear them.
