I'm not particularly bothered by any of the moods. I use UI Cheats and click most of them away. Fine is my preferred mood. I've always thought it was a bit of a hassle to try and get sims in a particular mood to complete tasks. Trying to keep up with the amount of an emotion produced by a moodlet just seems like more work than is necessary. I do remember early on trying to make sure my sims were in the right mood before going to work or working on a task but it wasn't fun. Now I just play and have my sims complete tasks without any thought to ideal moods. Some tasks may take longer to complete, such as skilling or work performance, but they eventually get done. I also don't use any of the emotional aura objects. Except for the berries from the tree of emotion when trying to solve puzzles in the temple in Selvadorado.
