Lifetime wish

The lifetime wish is part of an Sim personality. The wish they choose must have something in common with the traits the Sim has. For example, a Sim with Flirty Trait can choose the Heartbreaker Lifetime Wish.

It is required for a young adult or older in create a sim. A Sim must chose a lifetime wish during the game when growing from Teen to Young Adult, or when they are a Child or Teen and excel at a certain skill.

If your sim completes his/her Lifetime Wish, they will not be able to chose a new Lifetime Wish via Change Lifetime Wish reward.

Below is a complete list of the 48 Lifetime wishes available in The Sims 3.

With the Ambitious trait the lifetime happiness will increase 15% (rounded to multiples of 500). For example, a Sim with Gold Digger lifetime wish will earn 23,000 instead of 20,000.
