On the Sims 3 Ambitions, I know a way that you wont ever have to get a job but you will have as much money that you like.
Press Ctrl,Shift,and C all at the same time. Something will come up. Type in motherlode (no caps or spaces) then press the return key. (Enter.)This will give you 50,000 simleons. You can do this as many times as you want to. You can only get up to 999,999,999 simleons though.
Happy Gaming! ^_^ Moemoerocks
P.S. If this is very useful to you because you don't want your sim to get a job then please rate this THUMBS UP! Thanks!
when you start a game go to edit town and move people out of their homes and move them in to your house then move them out and if you keep on doing this you will be rich and the town people will be poor so that is all you have to do.
