Dead plants
When a plant is dead, do not throw it away. You can sell the dead plant for as much as a new plant costs.
Easy money
When you go to a house and do not have much money, trade in all the wallpaper and buy the cheap version. You can get a good amount of money. You can do the same thing with the tile.
Fishin' For Profit book
To get the Fishin' For Profit book go to Nikki Nack's store (open from 9 a.m. to 5 p.m.). After you buy it, find O'Phil Mclean. Give it to him and he will give you a job. Note - You must get the goals from him first. To do this, talk to Salty. Later in the game, you will be offered by Nikki Nack to buy the Waterfront Villa for 3,000 Simoleons.
Never work
In Bustin' Out mode, the people who you live with cannot get fired. If you want them to stay home, just let them. This can be very useful if you need them to clean up, or need them to do some other things.
While living with Mom, do not run out and get a job after you have completed the first few goals. Instead, stay around awhile and use that time to build skills. Mom will nag you, but just select 'Okay' and keep doing everything else. Make sure to keep yourself happy and entertain/talk/joke with Mom to keep your relationship up to par. When you have your skills where you want them, move out. This will make things much easier. You will then be able to concentrate on your job and relationships, rather than skill building.
Skipping work
In Bustin' Out mode, you can skip work by moving back into Mom's house. While you live with Mom, the bus will not arrive, and you do not have to work. This is useful if things are not going so well and you need some time to "restore" your Sim.
Throw an art opening
When you move to Studio 8, one of the goals is to throw an art opening. In order for the art opening to be successful, you have to purchase a Sculpting Block and sculpt it first. Then, have the party and it will be successful. However, before you can purchase the Sculpting Block, you must complete the goal that will give you access to it.
Permit Cheats
Pause the game in Bust Out or Free Mode and use the D-Pad and/or buttons to enter the following cheat(s):
L, BLACK, RIGHT, BLUE, LEFT (this creates a gnome on the Sim's property signifying cheats are allowed); you can also click on it to gain money.
