Paula wrote about a teaching dream she had, and it made me laugh a bit, although the laugh of sympathy. I frequently start the semester with any number of teaching dreams: forgetting where my class is, trying to teach two classes at once, completely forgetting what subject I am teaching, etc. Teaching can be stressful business.
But I also really like Paula's analogy with parenting: you worry that you are doing everything wrong, but your children turn out to be alright in the end. I would add, that if they don't turn out alright, it isn't necessarily the parent's fault ; )
As teachers, we need to believe in what we are doing, and trust that students will meet us half way. It is good to question, reflect, and improve upon our teaching, but we need to be careful not to try too hard. Sometimes we twist ourselves in knots trying to teach the perfect class or cover all the bases, and what is need is less, not more. Sure the postmodern architects like to say "less is a bore," and we need to keep that in mind too, but sometimes less really is more.
