Lifetime wish

The lifetime wish is Sim's ultimate goal throughout their lives. Sim's lifetime wish is related to the traits they have. For example, a Flirty Sim may want to have the Heartbreaker Lifetime Wish. As of Late Night or patch 17, the game allows player to choose any lifetime wish, even if it does not correspond with their traits.

It is required for a young adult or older in Create a Sim. A Sim must choose a lifetime wish during the game when growing up from teen to young adult. Sometimes, when a child or teen excels at a certain skill, they will receive a lifetime wish in their wish slot, which they can choose to promise or not. The game will prompt if the player clicks it. If a child or teen picks a lifetime wish, they will not need to pick one when they become a young adult.

Once a Sim has completed their Lifetime Wish, they will not be able to choose a new Lifetime Wish via the Change Lifetime Wish reward. If a Sim uses the Change Lifetime Wish reward, the amount of Lifetime Happiness Points on the wish the player changes to is reduced by 10,000.

On The Sims 3 for consoles, there is a glitch that allows the player to have any Lifetime Wish they want, regardless of Traits, on the Create a Sim screen by choosing a trait that inspires a certain Lifetime Wish (like choosing "Evil" for "The Emperor of Evil") and then hitting Undo, allowing a Sim to get back the original trait they had without losing the Lifetime Wish they just chose.

There are several ways for a teen or child to trigger a lifetime wish. Often, being mean to another Sim and/or beating them up will trigger the Emperor of Evil or Super Popular wishes. Watching a Sim die will trigger Emperor of Evil, World Renowned Surgeon, Star News Anchor, or Creature-Robot Cross Breeder. Seeing a ghost will often trigger Creature-Robot Cross Breeder. If a parent gets promoted, the child may roll a lifetime wish with the career of the parent, or even a rebellious career wish opposing the parent's career if the parent is working either in Law Enforcement or as a Criminal. Dining at a Bistro may trigger Celebrated Five Star Chef. Watching a game at the stadium or working out may trigger Superstar Athlete or  Perfect Mind, Perfect Body. Witnessing a burglary may trigger the Become a Master Thief,  Forensic Specialist: Dynamic DNA Profiler  or International Super Spy wishes. B eing read to sleep by a logic book or playing chess enough will trigger Chess Legend, and occasionally gaining a skill point will trigger Renaissance Sim.
