This guy's a very, very great poet. One of the best I've seen.
I'm not sure if I fully agree with everything he's saying, though. But that's a problem I have: the better something is, the more likely I am to nitpick (because bad things aren't worth that attention, and good things are). For example, depression is an illness like a cough. It's alright to consider medication as part of a treatment. He's right though, that it doesn't solve everything.
The title also is something of a misnomer, as this wouldn't stop a bully so much as cheer up a bullied kid. In fact, it doesn't do much to talk about the root causes of bullying or how to prevent it.
It is very, very good though.
