Ever made an "average Joe/Jane"?

I'm currently playing two average Joe's in TS3. Both of them will never achieve their Lifetime Wishes and they only have a part-time job each, no careers. They are more distinguished than your example though since both of them work quite hard on their skills. The wife is climbing up to mastering fishing and has a decent diving skill, but since she lives in Sunset Valley she can never achieve her scuba diving goals. The husband is a good sculptor but I plan on never making him particularly good in painting, thus not completing his Da Vinci LTW.
Both their children are artistic, but both of them will also not "excel in life" in the typical manner. The son will be a good painter but also an airhead athletic jock, never achieving his master painting LTW bc of spending most of his time in the gym and getting juiced with his high school friends instead of truly mastering his craft. He will, like his parents, only ever have a part-time job. He won't ever marry because of commitment issues, but he will be family-oriented, being more than happy to help raise his sister's child. His sister will be self-employed but keep most of her sculptures and paintings so she honestly won't bring a lot of income- she is thus a bit of a freeloader on her parents, spending her days on her two hobbies. I plan on letting her complete her LTW, but she will have an unplanned pregnancy and not know who the father is, as previously mentioned. Her parents and brother will have to do most of the parenting since she'll be more interested in her art than her kid.
