I tend to have Sims in the creative arts; painting can be quite lucrative (especially now with Plopsy), and if a Sim completes the Painter Extraordinaire aspiration, not only can they paint all the emotional paintings regardless of mood, they can write all the emotional books (Playful Book, Romance, Sad Book etc.) when they reach the right level and carve all the emotional woodcarvings regardless of mood, so it might be one of the most useful of the aspirations. (It's also one that technically can be finished before a teen ages up to YA, at least if you play on Long lifespan.)
