The video clip doesn't provide much context for Bliss' outburst, but the speech, whatever preceded it, stands on its own. It's what every bored and disaffected public school student has always wanted to say but dared not to.
Bliss preaches:
You want kids to come into your class and want them to get them excited for this, you gotta come in here and make 'em excited. You want a kid to change and start doing better, you gotta touch his frickin' heart. You can't expect a kid to change if you just tell him. You've gotta take this job serious. This is the future of this nation. When you come in here like you did last time and make a statement like 'Oh this is my paycheck.' Indeed it is. But this is my country's future and my education. But there's a limit when I'm not bitching but simply making an observation.
Well said.
