Too much of a good thing

So I've already done 5 hours of instruction this week, I've got 4 more coming up today (!), and 2 more tomorrow, to make a grand total of 11. I know some people probably do that much instruction every week, but it's a brave new world for me, and it's made a lot more difficult by the fact that I've got 6 entirely different groups of people I'm talking to here, with very little that can be recycled between the various sessions. Come here again on Saturday and see if I'm still alive!
