Change an exisisting Sim?

[Mvnl]

Is there any way/cheat to change a Sim that's already finished?
I build one I really like but I regret some of the habits I selected for her, so I'd like to change them, but it feels like a waste of time to try rebuilding her exactly just to adjust her personality a little..

Anyone can help me out?

If by habits, you mean Traits. Open the cheat box. Type "testingcheatsenabled true" (without the quotes).

Then Shift + click on your Sim. Should have the option to "Modify Traits".

If you have enough point from the lifetime whish you can buy the option to change some things on the personality. Altough I never tried just read it in the description.
