For the goal of getting a job, my sim always refuses, she says she is too depressed but the MOM is too lazy to do any work so She has to do it and she becomes depressed!
Does anyone know what I should do to get her happier?

Fill up her motivations so they are in the green.

Comfort: Sit down/sleep
Energy: Sleep
Hygeine: Take a bath or shower
Bladder: Use the toilet
Room: Clear up the mess (since you can't hire a maid yet)
Social: Talk to others a lot; I have a feeling you can only talk to Mom right now, unfortunately
Fun: Do something fun; dance to music, read a book or if the TV is fixed, watch TV
Hunger: Cook some food, or if you don't have enough cooking skills, dial for a pizza

I think that covers everything

THiS HAS HAPPENED TO ME BEFORE. ALL i HAD TO DO WAS TURN ON THE MUSiC, DANCE, WATCH T.V., TAKE A SHOWER, GO TO SLEEP THEN iN LiKE THE NEXT FEW DAYS, EVERYTHiNG WAS GREEN AND THEN MY PERSON WAS FiNALLY LOOKiNG FOR A JOB AND GOT ONE.

I just told him how to build motives. Stop trying to get one up on everyone. You don't need to post in every thread.

just put in the cheat freeall and upgrade everything so the stats raise faster!

It's very easy getting a job just look on the computer if you bought a computer or look on the newspaper outside.
make sure you keep your sim in a good mood cause if you do you have a chance of getting a promotion.
