"I'm a mechanic. What's wrong with being good at driving, Dom?" Fast & Furious
"I'm an IRS employee. What's wrong with checking your CIA tax evasion and catching a couple of moles while I'm at it, Tom Cruise?" Mission: Impossible
"I'm a courier. It's only natural that I run a little fast, right, Flash?" The Flash
"I'm a personal trainer. Is there anything wrong with being a little stronger, Clark?" Superman
"I'm a wandmaker. Isn't a little magic just part of the job, Dumbledore?" Harry Potter

One world, one profession: mechanic, federal agent, mercenary, sailor, photographer, police officer, magician, wandmaker, therapist, designated driver, programmer... There are no jobs I wouldn't moonlight in, only ones you haven't thought of. If you're curious about how a profession from the real world, or from your dreams, might play out in another world, post the world and profession in the pinned thread. Perhaps Kan Meng can give you a satisfying answer.
Lastly, thanks to the blurb for The Travelling House of the Film World for inspiring me. I couldn't get in touch with Dayu, but I'll thank him personally once I do.
