Careers fairs

Just read Seth Godin's blog about the uselessness of careers fairs.
What I would like to know are his ideas on how we should help students learn about the world of work.
I was intrigued by
"There are average jobs, certainly, average in that they require people to fit in, do what they're told and follow the manual. I'll grant you that those jobs need to get done, but I'm not sure they have to get done by you."

Would not most jobs fall into the above. Most of us do what we are told and follow the manual to some extent and still have chances to be creative, proactive and innovative. What is wrong with doing such a job? Certain tasks need doing everything, every week, every term or whatever. Even the most creative of people will often have to follow the brief or ideas of their client.

When I plan lessons etc with teachers I enjoy it and find it stimulating, but then I might have to deliver the same thing 10 times over to each teaching group.

I wonder what jobs Seth thinks do not fall in this average job category?
