I clean carpets, floor tiles, & woodfloors with my dad.  He's getting up there in age, not sure what'll happen.  I mainly have a lot of problems with social anxiety, & dealing with customers...well, yeah.  Some are pretty easy, but some are demanding, arrogant, & like to stare at me while I work.  What happens then?  I can't concentrate on my work, because I can physically FEEL their eyes starting at me.  What's funny, is that I feel like I'd have no problem if they were watching me on camera, but, with them physically there.... :/  I also have a hard time in general talking to people on the phone, & have unreasonable anxiety(as if any of my anxiety is reasonable) in thinking that I'll say something stupid, or be misunderstood.  In any case, I'll just see what happens & wing it.
Also, partially due to my lack of self confidence to run the business(but also to help pay the bills), I work for my brother at a warehouse down the street from me.  He buy re-furbished diapers & syringes & sells them for profit, & I catalogue said diapers & syringes, oh, & sometimes re-furbished condoms.  Seriously though, he buys & resells electronics, toners, etc.  Random stuff.  So far, I just try to find time(& energy) to do some inventory atleast a couple times a week after my regular job, usually on Wednesday nights & Saturday afternoons.  I basically just go thru stuff he has ready for me, look for part #'s(if there are any) or any other kind of markings, write them down, take various pics, weigh them, & put them up on shelves.  If VERY boring, but, I don't have anyone I have to deal with looking over my shoulder.  Actually, it does get lonely there, especially when I'm there late at night. :/
Just kidding. I'm working in an engineering office and design facades for buildings. Lots of glass, steel and aluminium involved. Usually I sit at the desk using AutoCAD, but every now and then I'll pay our sites a visit and help the mechanics with the installation. Fun, fun, fun.
My wife got a degree or whatever for AutoCAD at ITT.  It sounds like you do, what she used to do.  When we were dating, she working for Western Pacific Industrial Structures, & making decent money, but they moved down south & the trek got to be a bit much for her.  She ended up at Home Depot for a while designing kitchens & did that for several different places using AutoCAD.  Nowadays she doesn't use it as much, but she works at Lynda.com & re-arranges offices there, & does hospitality & stuff.  It's a long, but nice drive there, decent pay, & (thankfully) they have good health insurance.
