1. Some students we get in physics courses should not be trying to do physics.
2. Most students should be trying to attend all of the scheduled classes.
3. Many of our students don't put enough time and effort into their classes.
4. Some students want ME to do work that THEY should be doing.
5. Students should not be expecting me to entertain them.
6. We should do things that are important because they are important, not because they are "fun."
