Playing 3 or more Sims in a household, is it difficult for you too?

I have a relatively relaxed playstyle, I let my sims enjoy life and waste their time. I do also have some set goals for them, but don't mind if it takes some time. You could try long life span it's a lot more relaxed - or aging off of course. I enjoy playing families of four, but I admit five is starting to get a bit busy for me.
