Dear Maxis, please add more traits and aspirations!

Wouldn't it be cool if the experiences and activties of kids and teens actually formed their personality likes and dislikes? For example, a teen who plays a lot of video games might form a "like" for sci-fi or fantasy, or make them more likely to befriend a magician. Or one who reads a lot of romance novels earns a bookworm trait and a romantic trait. Someone who never went swimming might end up a waterphobe and hate swimming later (or even risk drowning). Or a kid who draws a lot or makes crafts might become artistic, giving boosts to crafting skills later in life. I know that sounds complicated but even a simplified system would be awesome!
