Motive

Motives, or needs, are the basic physical and mental requirements or desires of Sims and pets in The Sims, The Sims 2, The Sims 3, The Sims 4, and The Sims Social games. In The Sims 2 and The Sims 3, Sims in different life states may have different motives, and some motives will drop faster or slower depending on a Sim's life stage.

Basic motives
In The Sims Social and The Sims FreePlay, fulfilling motives/needs will make the Sim inspired, and inspired Sims will earn more simoleons. In FreePlay, giving a Sim a cupcake will instantly fill the Sim's motives.

 * Social
 * Hygiene
 * Fun
 * Room/Environment (Moodlets in TS3)
 * Energy
 * Bladder
