It can be overwhelming to start a new save. I can relate for sure.
I start with a character in mind and try a new career or a new world or even a new life aspiration.
I play in rotation and my most entertaining save is the one where I spent an evening creating sims in cas and placing them in the same world, San Myshuno, and had them varying jobs I hadn't tried or done in awhile. It was nice to see all my new sims in the same apartment complex and to build relationships.
I'm up to about 40 households now (I started with 4) and they are all expanding into other worlds. From singles they've become families. When I move one Sim or sim family I put in a new one in Myshuno. For me it's either "escape city life" and they have to save to do so or they love city life and move into better apartments.
Start simple, pick something you enjoy or want to try and just remind yourself it takes time and to just enjoy the process.
