Back to School Adrenalyn

First week of September. It's like I never had the summer...I wake up before the alarm goes off. I'm out jogging five minutes later, shaking out the anticipatory tension of the day. I get going with my lesson plans like starting a cold engine in minus 25 celsius weather. It takes a lot of energy. On the one hand I'm rested and ready, on the other I'm out of routine and rusty. I want to maintain an interactive language learning environment. Will I be able to keep it up so the seatwork doesn't become the norm?
