The Sims Online:
Fun

All work and no play makes your sim a dull creature! If you just work non stop on learning how to cook, your sim is going to balk and insist you do something more enjoyable. This can be playing pool, reading a fun book, watching TV or all sorts of other things. Some money making activities like painting a picture are fun too!
