The same lessons I learned in highschool 15-ish years ago. 

Violence is the only way to stop a bully. You either jump him with your friends after school, follow him on your own, or try to retaliate in school. 

Nothing will change until they're in severe pain. They need to fear you whenever they think about you. That's the only way a bully will stop.

I've been saying this for years. People look at me like I'm nuts, but I learned that lesson the hard way - you gotta get on their level because it's all they understand.
