This trick requires a TV with a Cooking, Fishing, or Gardening channel
and a video game system. Have a Sim sit down and watch television.
Switch the TV over to one of the previously mentioned channels so that
the Sim can start earning his or her skill point. Then, have a second
Sim go over and start playing video games. Notice that although the TV
is displaying video games, the first Sim still has the skill meter above
their head. Allow this Sim to sit there for as long as they please until
they decide to do another activity of their own. After that, the skill
meter should stay above their head until you start another Cooking,
Fishing, or Gardening skill activity. As an added bonus, you can train
two skill points at once. For example, work out and both the Athletic
and Cooking skills will continue to rise. If you keep repeating the
steps until each skill channel has been viewed, the Sim will keep
learning the three skills as he or she goes on about their daily life,
and four when doing skill activities.
