How do you handle the rotational play hydra?

I keep aging off most of the time, but I now have too many played sims as I add a new sim or family occasionally, and often play premade sims too. I have decided to not play some of the premades I was playing. I also make ( or download ) a lot of venues/community lots so my sims have a lot of things to do. My sim households are all different. Some nuclear family, some roommates, some brother and sisters, a grandmother and granddaughter, single parents with a child, a generational family that has 4 grandparents, mother father and 2 children. And some single sims or couples. A few households have animals. Households have varying wealth levels, many have active jobs. Some households focus more on family, others on careers, some love taking vacations. Some socialize a lot. This way rotational play is less boring,
