1. Give you Sims their dream career by firstly entering the cheat 'testingCheatsEnabled true'. Then Shift + Click on the mailbox of your home lot and select 'Set Career'. You can then choose any career or profession at any level for your Sim!

2. Have your Sim blow up almost any object! It's true, when your Sim reaches level 5 of the inventing skill, he or she can blow up almost any household object, even if it's in a friends house or on a community lot! (Beware of some hefty fines though...)

3. Instant money of any amount (without motherlode or kaching) Open the cheat window (Ctrl + Shift + C) and type in 'familyfunds' followed by a space, then the families name followed by another space and then the amount of money you want the household to have. This can be a bit difficult to follow so I'll include and example.

If you wanted the Goth household to have $24,000 in total, you would enter: familyfunds Goth 24000

Thanks, and enjoy :-)
