If your Sim is very depressed or has another low attribute, enable the "move_objects_on" code and pause the game. Click on the Sim in buy/sell mode and click the bottom of the screen to delete him/her. Once deleted go to the live mode and double clock the person's head icon to go to where that Sim is located. Everything should be close to full. Note: Save the game immediately before performing this cheat, or you will lose any career changes or points you have earned.
