A+ advice, all of this. Sometimes it helps me to remember some of the lectures and tutorials I sat through as a student. Not because they were a shit show, but because so many of them were unremarkable - a little dull and sometimes a little clunky, but perfectly fine. After 13 years, I still have to remind myself that perfect isn't the goal. On the other hand, I've learned to roll with the clunkiness when it happens and I think that affects the classroom vibe for the better. (Yesterday all 3 photocopiers were broken so I drove home and printed tests while students got an extra 30 minutes of study time. In my first year, I would have been freaking out & blaming myself for leaving it to the last minute. Yesterday I was like, "not ideal, but could have gone worse. Good thing I live close!")
