If you need cheats to get you through Sims 2, then you aren't very good at games.
Create character.
Get a job.
Have aspirations at gold and get the Noodlesoother and wear it just before going to work if you have all the prerequisites for promotion. Promotion in one shift.
Keep promoting until you reach the top. Easy.
It gets easier with University expansion pack.
Get the Natural Scientist job. When you reach the top you work only 1 day and get $10,000 and all your Wants become full except Hygiene. When they get home send them straight to the shower and you have the whole week free.
Make sure you get a good bed and send them to sleep at around 1:30 AM and they should wake up by themselves around 6 - 7 AM.
This is not a hard game.
