You should buy for satisfaction points some bonus
The name of this bonus is "quick learner" or similar.
Nevertheless, Sim teaches relatively quickly if he spends a few hours a day practicing charisma in front of a mirror.
Of course, you can use codes. Unfortunately, I do not know the name of this code, because I do not use the codes. With the codes, the game is too easy for me.

The Savant trait works well for this.
