I never tried the art appraisal career, so I have no idea how many ops it brings. Once she's done with that career, you could place her in another rabbithole career with guaranteed ops. Or have her be a temporary Private Investigator since PI cases are treated as ops.
I really hope she succeeds, by the way!
It has next to none, hence why I was mostly relying on skill opportunities. They provided until when she got into the middle of her adult stage, then I just kept getting the same ones over and over. She's highly skilled in painting, photography, and fishing and SuperMaxed street art, so I figured that I'd get way more than what I had.
I'll have to look into becoming a PI. I'm sending her to university to see if I can get anything out of that (I did get one from merely taking the test, so I just need one more).
I hope she does, too. I'd hate to crash and burn when I've just gotten generation five into the picture.
