great news! There's a way to get satisfaction points without third party cheating software. Here's how:
turn on testingcheats true
select aspirations you know your sim really wouldn't work on. Like if your sim is a loner, put on the popularity aspiration
input this into the cheat box: aspirations.complete_current_milestone
What this does is it completes the current tracked aspiration's goals/milestones, and gives you their satisfaction rewards. Do this with a few aspirations and you will have enough satisfaction points to get all the traits or even just the traits you really want.
