Should I go for the teaching assistantship?

Should I go for the teaching assistantship for Decision Support Systems? If I accept the job, I'd be handling the lab sessions for the course.

Is it something I'm excited about? I like teaching. The professor seems to care about teaching as well, and he handles the tutorials himself. That's good. I'll probably learn a lot from him. Does the subject itself excite me? Browsing through the textbook turns up a couple of interesting stuff that I'll be able to use in groupware research and later on. It's a good opportunity to learn about organizations' information needs.

Does it fit into my long-term plans? I'll learn about information organization and visualization, which might be useful for executive coaching later on.

Is it worth 6 hours a week or 78 hours of my life? I guess so.
