What do you do in The Sims that you really need to stop doing, but keep coming back to?

Isolating my Sims. I am an introvert myself and I have found that I tend to isolate my Sims from outsiders. I realised that when I was playing rotationally and went into one of my favorite households which was actually the second household I played in my saved game and saw that both men had a HUGE amount of people in their relationship tabs and a lot of friends. Friends they did NOT have when I branched out into other households. Now, I consciously (and on more than one occasion had to kick myself figuratively in the tuckus) make my Sims say yes to phone invites and actually answer the doors when visitors come-a-knocking. I've even had them hold a party or two that was not a requirement to finish up an aspiration.
