Be enthusiastic! Be excited! Be willing to fake it if needed (until the enthusiasm becomes real) even if that means two Mountain Dews instead of one!
You know those days when you wake up excited to go to school, because you get to teach something really cool. I think the idea here is that we all (students and teachers) need more of those days. And it doesn't happen by accident. It happens through putting all these elements together. It happens when you make a conscious choice to make each day exciting. It happens when you teach like a pirate!
