I've decided I need to add to my list of things learned while student teaching. Here goes.
1. How to park diagonally backwards.

I wouldn't say I'm an expert at this - YET - but I've gotten significantly better. My wheels are now mostly parallel with the white lines!
2. How to stay awake while observing private lessons.

(Note: this is NOT me - shocking, I know - nor is it during a flute lesson. It's just a funny picture.)
Tips to those who also need this skill: write a letter to someone in outline form so it looks like you're taking notes; get an instrument and play along, even though the 5th graders are significantly better than you; drink water when you find yourself struggling to keep your eyelids from melting; tell your teacher that everything you learn during the day is absorbed while you're asleep and that you're just attempting to hasten the process.
3. As previously mentioned, how to write a letter in outline form.

If you're awesome, you'll write it in cursive just for the practice of improving your handwriting.
4. How to remain oblivious and invisible while overhearing things in the teachers' lounge.

(I take no credit for this cartoon. I hope it's legal to post it here.)
Because I can achieve this state of being, I feel it is not necessary to say anything about it. I might no longer be both oblivious and invisible.
5. How to get small children to think you're cool.

-Fix their instruments when they break them. It's inevitable.
-Sing for them...on pitch. They'll tell you to go on American Idol, regardless of the fact that you are not a voice major, nor should you be.
-Learn all their names in a class period; they'll think you know EVERYTHING.
-Don't talk to them like you're a million years older than them.
-French braid your hair without a mirror.
6. How to explain things a thousand different ways.

Sometimes you need to get your point across to different learning styles, so you have to say the same thing using different words. Or you need to teach something clearly to a wide variety of students, so you explain things using other vocabulary. Or you must synthesize your main points into a cohesive statement that appeals to everyone, because of Howard Gardner's theory of multiple intelligences. Or, to put it metaphorically, it's like reharmonizing your chord progression, but every time you come back to the tonic. Got the point yet?
7. How to get ready in the morning really fast.

(I think I need this alarm clock. Getting up would be so much more fun!)
I like to maximize the amount of sleep that I get to the point where I get up at the last possible moment that I can get up and still be on time. Let's just say my alarm goes off at 5:45, and I don't get up until 6:25...and I need to leave at 6:40. Ish.
I could probably keep going, but I think I should stop here, because maximizing the amount of sleep I get should probably include going to bed really early. If I'm going to do that, I need to start getting ready now. Go.
