What CAN be done to fix TS4?

Not sure if this has been said, but we should have more options for ambitions! I like that we can change them at any time, but I always feel like I get into a rut when trying to fulfill ambitions. I wish there were an independence ambition, for example, for gamers who want their sims to be more self-sufficient. I think that'd create interesting gameplay - how to garden food and live off that, how to live off royalties from crafted objects/songs/books, etc.
