I might be in the minority but I play with all of my sims. I typically don't focus on one single sim but on all of them. That can be a challenge in a big household but I still do it. I use the pause button to then line up actions for them. If they autonomously decide to do something I might let them continue doing it but I generally come up with a series of actions for all of the sims.
I'll rotate from a big household to a smaller household when I want a break, but I guess I find it interesting or easy. If anything, it takes a while to fill up the needs of all the sims in bigger households, but I manage it. Sometimes I send them all out to a venue together. I guess I like managing groups of sims. Sometimes, I like the ease of playing a smaller household though.
I mentioned this elsewhere but I generally have some concept of what motivates any given sim. It sounds complicated but it isn't. "Here's Jane Sim, she's the mother of the household. After her much needed shower, breakfast and caffeinated beverage of choice she will either spend time with her family or enjoy a little time to herself. Does she have any chores to do?" Line up a series of actions and check on her later or glance at her as she's at some stage in the activities. If I have a specific plan then obviously that takes priority.
