Rags to Riches:
At Mom's house, Mimi's place, or Dudley's trailer, continue to make purchases until you posses less than $100. Wait for about an hour of game time. The phone will ring and when you answer it you will receive $$$. Just repeat this until you have desired amount of wealth.
Become a Mommaí¢â‚¬â„¢s Boy (or Girl):
At the beginning of the game, don't get a job. Stay at Momí¢â‚¬â„¢s House building up skills and making friends. Since several motives doní¢â‚¬â„¢t decay at Momí¢â‚¬â„¢s (most notably energy, so you woní¢â‚¬â„¢t have to sleep) and you doní¢â‚¬â„¢t have to go to work, youí¢â‚¬â„¢ll be able to build up skills very quickly.
Take Time Off for Personal Development:
If you havení¢â‚¬â„¢t fulfilled the necessary requirements for a promotion, move back into Momí¢â‚¬â„¢s House. Instead of spending an unproductive day at work, youí¢â‚¬â„¢ll be able to build up your skills and make friends. When youí¢â‚¬â„¢re ready, move back into the appropriate lot and nab that promotion.
Call a Rich Friend:
Create two Sims on two memory cards. Load one, sell everything at Momí¢â‚¬â„¢s House, and save. Load the other and allow the Sim who sold everything to join as the second player. Make the rich Sim empty his or her steamer trunk of money. This should net you about 50,000 Simoleans. Repeat at will.
Rely on Charity:
Spend all of your money. When you do, you should start receiving money via telephone calls. As long as you keep draining your account back to zero by buying more stuff, the calls will keep coming. When youí¢â‚¬â„¢re done, sell everything you bought.
Become an Alcoholic:
Drinks made with the drink bar refill energy, fun, and food. If you turn your roomies into drink mixing extrodinaires youí¢â‚¬â„¢ll never have to sleep, eat, or worry about fun.
Fishin For Profit:
To get the Fishin for Profit book go to Nikki Nack's store (open 9am to 5pm). After you buy it go find O'Phil Maclean, give it to him and he will give you a job. You have to get the goals from him first; to do that go talk to Salty. Later in the game you will be offered by Nikki Nack to buy Waterfront Villa for 3,000 Simoleans.
