If you do business (by any means), 99% of the time you need to do stuff you don't like. I don't think he loves spending 1 hour to explain a teacher something step by step. Or write documentation for end users and millions of other small non-techy, non-fun stuff.
If you make money either from you own business or someone else's you have to do not-so-fun stuff all the time. That's the reality. Amount of not-so-fun stuff can change massively though.
You either slave of your boss or of your own customers :)
