I'm working on an ISBI (I'm Surrounded By Idiots) challenge, which is one where you can control only one sim per generation. I'm on Generation 4, and her aspiration is to become a Public Enemy. I'm writing a story about the family -- Koehlers' Kraziness, in the link below.
My other project is the Straysim Academy: 1 adult, 6 children. My plan is to age up each child as soon as he or she has completed a child aspiration and gotten an A. Once they're teens, they have to get an A, reach the top of a teen job, and complete the first milestone of their aspiration. At present, my 6 children have A's, but no one has completed an aspiration, although they're all working on the 3rd milestone.
