The whim system is awful. All sims get the same whims.
Research vampires
Make a friend
Get a cat condo (even if they don't have a cat)
Buy dishwasher
Build 1x1 pool
Buy a puppet theatre
Play an instrument
Buy an instrument
Whims don't make sense for the characters and there's very rarely anything substantial unless you manipulate the lot with adding specific lot traits. The sims 2 and 3 have a much better system where the wants and wishes actually are specific for that sim. My romance sim in 2 would not get whims to have children and likewise my family sim would not get wants to kiss or woohoo with x amount of sims. Even in 3 they get specific wishes tailored for them. But in the sims 4 my sims can get the same whims in the same household. I spend a lot of time clicking away random whims that don't mean anything.
