Adult Sims can get skill points in cooking, mechanical, charisma, creativity, body and logic. Sims can use these skills at home and for getting higher up in the career track. When they need skill points to get promoted, the skill points they need will be underlined on the Job subpanel.
Cooking skill points can be obtained by reading a cookbook from a bookshelf. Meals made by Sims with lots of cooking skill points will satisfy the Hunger motive more. Sims with lots of cooking skill are also less likely to start a fire when cooking with an oven, microwave or barbecue.

Mechanical skill points can be obtained by reading a DIY book from a bookshelf, unclogging a clogged-up toilet, repairing a broken object.
