I definitely use the Practice Makes Perfect trait, and my SuperSim that I've been working on has completed the aspiration for the Enhanced Kleptomaniac trait-- I'll be honest, I hate it. My sim is currently a police officer and if I look in the wrong direction for too long, she swipes things autonomously. I wouldn't mind if it was player-directed, but if I send her to work without me she comes back with something every single day that she stole from the POLICE STATION. She even stole one of the desktop computers! The others I haven't had cause to use yet but someday I might.
