Let's Find Those Trait Improvements

Let's do an experiment. This is Paola, and I have edited her to give her the traits Neat, Goofball, and Cheerful, the three traits I've seen people post about that seem to have the most autonomous/noticeable changes. Will one trait be dominant over the others? I don't have time to play tonight, but stay tuned ;)

Also, please share your own observations about sims who have multiple traits that got improvements. I'm curious to see if they balance each other out, or if one seems to dominate the others.
