 For me is that I'm much more challenged, I'm much more engaged, I'm having a lot more fun in my classes. And that's terrific. That means that I can sustain what I'm doing for a lot longer. The payoff, the bigger payoff, the more important payoff though, is that the students themselves are coming out of our classes not just with a set of tools and a knowledge base, but they're also coming out with the ability to thrive in a dynamic environment. So they can change as the industry changes, as their work environment changes, as their responsibilities changes, because they have the critical thinking skills and the creativity to take those capabilities that they've developed and very confidently adapt them to a new space. And that's what's going to help them to thrive. They'll be able to pick up new tools on the way. We have to train them to have the courage to do that and the understanding of how to evaluate a situation and know what it is that they need to change about themselves to adapt to that. Think about educating future marketers. Then we really need to think about what is happening in the industry today. It's a rapidly changing environment. Marketing as it's practiced today is radically different than it was practiced 10 years ago. We need to prepare students for being marketers today. We also need to prepare them for the changes that they can expect to see in the first 5 to 10 years of their careers. So the last thing we want to do is send them out with just a toolkit and have that toolkit be something that's obsolete. So what critical thinking does is it allows them to recontextualize the concepts that they've learned, the principles that they've learned, the tools that they've learned into new environments.
