Charisma

Charisma is a skill in The Sims and The Sims 2. It is a surprisingly unused skill that is used mainly for some careers. It can be learned by talking to oneself in the mirror.

The Sims
In The Sims, Charisma can be learned by talking to oneself in the mirror or medicine cabinet. In House Party, Charisma can be increased by using the Super Schlooper Bubble Blower or playing the 'Bezique's Folly' Card Game with other Sims. In Unleashed, Sims can talk to the Parrot or Cockatoo to increase their Charisma, whilst Superstar adds the Face of Shakespeare bust, which can be spoken to to increase Charisma.

The Sims 2
Charisma in The Sims 2 is similar to that of The Sims; it is mainly used in certain career paths. With The Sims 2: Pets, it can also be built by teaching and talking to a bird. It is useful also to tell better jokes and decreases the chance of being rejected in a social interaction.
