A Sims 'Lockdown' Challenge?

I hadn't played Sims 4 for several months, but when the lockdown began I thought of playing sims in lockdown as well. It's what got me back in the game, but I'm afraid I didn't stick with the lockdown idea for very long. I did initially look at the room challenge, but the mansion baron is an aspiration I had already done a number of times before. There are many old ways to make money without leaving the home, but I wanted to do something new and I had a number of packs I hadn't explored yet (DU, IL, Strangerville). I tried to do the engineering career while my sim was in lockdown. I guess I had an idea that he would build a household of robots that would do errands for him so he wouldn't have to go outside. But eventually he had to attend or give lectures at the university, and I didn't realize that robots were very high maintenance, so that whole idea just went out the window. The robot got shipped off to is now attending university, and my sim now has a significant other and has moved to Strangerville for his next challenge.
