Lifestyles: how's your experience?

I was about to make a thread asking about what lifestyles actually DO. My sim has developed the Outdoorsy lifestyle and I haven't seen a single new moodlet or change and it's bothering me because I was actively pursuing that and it seems like a waste of time if it does nothing. He also has the "People Person' lifestyle and so far I've seen him get a moodlet about being happy being around people since he was a people person. This same sim has "Single and Lovin' It" in progress. What is great is that all of these lifestyles actually fit his character perfectly. I just was hoping to see more noticeable change. Then again, he's only had the lifestyles for one play session.

Anyway, can people please try to be as detailed as possible with what each lifestyle they've experienced actually does?? I want to know so much more about this feature.
