The Sims 2/Needs

Every Sim has basic needs. Hunger, bladder, energy, comfort, fun, social, hygiene, and room. To fill hunger, buy a fridge and select it in live mood with your sim.

You will eventually need to buy more stock for your fridge, to do that use a phone and click delivery, and then groceries. To fill bladder buy a toilet. Select the toilet in live mood and click "use". To fill a sim's energy, buy a bed, couch or a recliner. When selected in live mood you will see, sleep or nap. Beds are best for a sim's energy. To give a sim comfort buy a seat of any kind, a higher-class toilet, a bathtub, a bed or a couch. Select any of the following in live mood: sit, relax, use, bath, sleep or watch TV. There are more options but these are the basics. Expensive couches are best for raising comfort. Fun can be raised by, TVs, toys, playing with another sim or entertaining, swimming, reading and lots more. If a sim is serious it would get more fun out of reading a book, if it is playful a toy would be best. Social can be raised by clicking on another sim a choosing any interaction, calling someone on the phone, the social bunny, talking on chat can all raise social. Kissing and woohoo are the most social raising interactions. Hygiene is important to your sim so buy it any of these: a bathtub, shower, tap or a mirror, which allows your sim to bush its teeth. Room can be raised by simply not being in a trashed room that has decorations in it.

When a sim's needs are met their work performance will improve, they can preform more positive interactions between other Sims, they can study better and they will spend less time throwing tantrums. While it may be fun to watch Sims suffer if their needs are not meet they may die and you will need to go to more effort to make another one.
