Even the lousiest teachers can teach you something...

Teachers are human and therefore even your grades are subject to their opinion. Seth Godin outlines the perks of having a teacher that is hard to please.

1. Grades are an illusion
2. Your passion and insight are reality
3. Your work is worth more than mere congruence to an answer key
4. Persistence in the face of a skeptical authority figure is a powerful ability
5. Fitting in is a short-term strategy, standing out pays off in the long run
6. If you care enough about the work to be criticized, you've learned enough for today
