Teaching

If you are going to take a class, commit.
Commit to the learning that you want.
Commit to the teacher.
Show up.
Do the work, or drop out.
Do your homework. And then more. Research. Try the stuff out in your life. Digest the information. Try it again until you can make it yours, or, discard it.

Teachers know more than they are teaching.

If you ask sharp questions the teacher will love it.
The teacher will know you're doing your homework. 
They can then toss more info your way. You both get to wake up.

Class is not for snoozing.
