By failing to prepare, you are preparing to fail.
You never know what motivates you.
If you've got a talent, protect it.
If you're going through hell, keep going.
Leap, and the net will appear.
The dog that trots about finds a bone.
Well done is better than well said.
I can, therefore I am.
To be a good loser is to learn how to win.
Never complain and never explain.
Besides the actual reading in class of many poems, I would suggest you do two things: first, while teaching everything you can and keeping free of it, teach that poetry is a mode of discourse that differs from logical exposition.
