I had this problem. Painting isn't fun for Sims and I played several of my own households. with the correct traits. And fishing isn't fun, either. Well, if it's not fun for my Sim why would it be fun for me? The game is supposed to be about the Sim. And if something isn't fun for them to do why would I make them grind? Neat Sims enjoying cleaning in most of these games, but sloppy Sims don't so unless I want to torture the Sim then why would I waste my time on doing this activity. Food for thought, EA.
