In which I give myself "very good advice"

Whilst my unhappy laptop is undergoing another scan, I've been getting ready for winter quarter, which starts tomorrow.  My main thought is Get there early.

I'm a creature of habit, and few things of daily routine are as important to me as getting a good seat in a classroom.  "A good seat" can be two or more of the following:

1. At the end of a row
2. On the right side of the room
3. Near the door
4. At a comfortable distance from the whiteboard and the professor

Most importantly, once I find the best seat for the given circumstances, it is essential that I arrive at class early, every day, to be able to sit in what becomes my chair.

If, for example, I get to class on time for an exam, I typically find somebody already sitting in my chair.  Somebody who rarely attends lectures but always shows up 10 minutes early for exams.  This event sends me to an uncharted area of the classroom, where I may or may not have to take somebody else's chair.  Said chair may be of a different make and model than my chair.  Ergo, I take the exam in more considerable discomfort than was necessary.  If I'd only got there early...

What about you?  Where do you like to sit, be it a classroom, theater, sanctuary, or conference setting?  Do you like to sit in the same place each time?  And why, or why not?
