I've though for a long time that most buffs are too powerful, and many too long. Especially ones for stupid things like cooking pancakes. In my opinion, most should be dropped down to plus one, except for truly emotional ones (deaths, weddings, someone throwing a drink in your face, etc). Then if a sim got mad it would take a lot of little things to over power it, not just vacuuming the floor. And most don't need to last 4 hours, either. Seriously, they do one little thing and they are happy, inspired, focused for the next 8 hours.
