Professions for just fun? Or also profit?

I feel that the Professions make a really nice profit on one end, but then there are more people that do it for fun on the other. Mostly because people tend to hang around and mingle whenever I see them after they obtain the materials that they need. Stuff like that, of course.

Plus, who wouldn't want to make something with both happy and relaxing music in the background? Ahaha.
