Yep, I've known a couple of "Motivational Losers" like that. One can teach almost anything except for "giving a shit".
Both were college graphic designers who felt they were above learning prepress. Nope...you're below it. Prepress is where the real education begins. Not interested? Then go back to designing your garbage and wondering why there isn't the money in it that you thought there would be...and "what's this miscellaneous art charge?"
