The Personality Mod
The Personality Mod adds 6 reward traits to the Reward Store. Each of these traits are inspired by the six Aspirations from Sims 2: Family, Fortune, Knowledge, Pleasure, Popularity and Romance. Each trait costs 0 Satisfaction Points, so you can add the traits to newly created sims, straight out of Create-A-Sim.
