Sims in the Pro Athlete career track suffer the greatest degradation of Hygiene during the course of the workday.
Body Points
Body points are the most difficult to obtain, but having an espresso machine (and a toilet) near the workout bench can help your Sim go several hours longer.
After the Tutorial
The tutorial house has the motives for Bob and Betty turned off until AFTER the tutorial is finished. Once Betty has appeared, just ignore the tutorial for a while ... get a job, and raise Bob's and Betty's skills. They won't need to eat, and instead of sleeping, they can use the espresso machine to recover energy that is needed in raising Body skill and going to work. In a relatively short amount of time, Bob and Betty can have all of their skills raised up to level 10!
Bonfire
If you need a quick boost of Room score, light a fire in the fireplace. Any of the fireplaces make a huge difference in Room score when they're lit. They work especially well when placed outside and lit just before going to work. Since the outside area is counted as one room, the fireplace will raise your Room score for you on your way to work.
In the Army Now
A good career to start out in is the Military career track. It is high-paying, and you won't need to worry about maintaining friends until your Sim gets to level five.
