I inspired every single one of my Sims to disprove that. A task going from 1 hour to 4 while spending SP or 8 while spending Simoleons is not due to a sad sim. It's a problem with the game. No item is required for the task, so again you are incorrct. The number of stars doesn't matter if the task doesn't require an item. If you don't understand the problem, refrain from trying to give solutions.
There’s no need to be rude!
The Sims in your screenshot, except Johnny, are smelly and sad, not inspired and not happy. If you had shown a screenshot with an at least happy Sim talking to Johnny, I would not have answered.
