Lifestyles: how's your experience?

My only experience so far was horrible. My sim went to Uni and gave a tutor session there to complete Academic aspiration. Immediately after it she got "People's person" lifestyle. Though she's actually almost a loner. She was cramming in Uni and nether was friendly with another sims in the dorm. She has zero notifications about working towards lifestyle and then bam... "People's person". Then she immediately became sad about losing a friend but she had a very few to start with and all of them were still friends with her. And then I was receiving non-stop notifications that all her family members were receiving the very same lifestyle "People's person". I'm sorry how another uncontrolled household is supposed to receive them? I've tried to turn this thing off. I received notification that all current lifestyles will be deleted. Great. I've changed the settings, saved and in several minutes received notification that another one of my sims received "People's person" lifestyle...

In the end I have to roll back to backed-up version before lifestyle was received. Turn them off there and go on pretending nothing happened. I think this feature need even more tuning and testing than NAPS. Also I have a feeling the design is badly thought. Why no lifestyles connected to crafting/creativity/music??? Too bad I have to disable and dismiss a new feature showed as innovative and game-changing from the start.
