Course Starting

My course begins this Tuesday evening. This afternoon, I did another run-through of my lecture, just to time it and fine-tune a few things. Took an hour and a half - I was aiming for two hours, but I flew through the first half. So I think if I slow down the delivery, I should be fine - not to mention the fact that I'll want to spend a few minutes at the start of the class talking about course requirements, etc., as well as getting a sense of the students' background.

But man, I'm exhausted after all that. By the time I finished the lecture, I was weary, dry, and feeling a bit light-headed. If it was that bad for me, how will the students fare?!?!

Poor kids.
